Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information storage device belonging to the field of information storage.

[0002]

2. Description of the Related Art Various optical discs such as MD (Mi
niDisc), CD (Compact Disc),
CD-ROM (Compact Disc Read)
Only Memory, CD-R (CD-Reco)
When an optical disk device that drives an Rdable), an OD (Optical Disk), etc. is used as an information storage device, for example, SCSI (Small Comp) is used.
It is common to connect to a computer as an external storage device through an interface such as the Uter System Interface). MDs, CD-Rs, and ODs are optical discs having not only a function of reading information but also a function of writing input information. By connecting the information writing optical disk device for writing information to these optical disks to the interface of the external storage device together with the information reading optical disk device, it is possible to easily configure a device for copying information via a computer.

FIG. 38 is a diagram showing a CD-ROM dubbing device disclosed in, for example, Japanese Patent Laid-Open No. 4-370566, which is a first conventional example. This CD-ROM dubbing device is a device (master device) for reproducing an optical disc which is a master for dubbing, and a write-once CD for dubbing data.
It is composed of a plurality of devices (child devices) for writing to, and a host computer for controlling the operation.

Further, under the control of the host computer, a CD disk recording device (master device) capable of reading data from the master optical disk and transferring the data to the slave device,
A plurality of CD disc recording devices (slave units) for recording the transfer data on optical discs loaded in respective devices to create a write-once CD, the master unit and each slave unit, and the write-once type It is provided with a serial line and an interface circuit for transferring the data of the CD disk to each slave, and a host computer master-master interface for transmitting and receiving control information for controlling the master.

When a user makes a copy of a CD-ROM, he or she operates the host computer to send a command to the master unit through the interface so that the master disc is reproduced, and at the same time, the master unit is reproduced by each slave unit. Control is performed through the master unit so that the data transferred from the master unit is recorded on the unrecorded write-once CD loaded in each slave unit. The data of the CD disk of the master unit is sequentially transferred to each slave unit connected in a subordinate manner, and written in each CD disc in each slave unit to create a CD-ROM copy disc.

As described above, in the conventional example, the host computer for controlling the dubbing operation is indispensable. Also, in the explanation of the configuration, it is stated that the master unit and the slave unit are connected to each other via the serial line and the interface, but it is not specified what kind of data is transmitted via the serial line. It is unknown about the specific composition.

As a second conventional example, for example, the magazine "MacLIFE", August 1993 (pp. 222-2).
25) article "Hardware and software for CD-ROM writers"
The method of recording a CD-ROM is introduced in. A second conventional example will be described based on this system. In this conventional example, only one optical disk device is used, but in the description, separate optical disk devices are provided for reading information and writing information for ease of understanding.
If the hard disk device 105 is used as an intermediary medium as will be described below, it will be apparent that one optical disk device can perform both functions.

FIG. 39 is a diagram showing an example of the configuration of an external storage device system capable of copying information using a conventional optical disk device. A SCSI interface 102 is incorporated in the host computer 101 as an interface to an external storage device, and an information reading optical disk device 103 and an information writing optical disk device 104 are connected to the SCSI interface 102. Further, the host computer 101 has a hard disk device 105, and 105 is also connected to the SCSI interface 102.

When the information of one optical disk is to be copied to another optical disk in this system, the master optical disk 106 is first reproduced by the information reading optical disk device 103, the information is sucked up to the hard disk device 105, and then the information is read. The duplicated optical disc 10 which has been transferred from the hard disc 105 to the information writing optical disc device 104 and loaded in the information 104 in advance.
It will be written in 7. There are two reasons for using this method.

First, at the time of copying, if the information writing optical disk device 104 once starts writing on the optical disk 107, data must be continuously transmitted without interruption until the end, but at present, Since only the information reading optical disk device 103 has a low information reading speed and it takes a long time to transfer the data, if the information reading optical disk device 103 is directly reading and transferring the information to the information writing optical disk device 104, the data transfer will be delayed. It will disappear and the data will be interrupted. For this reason, the above-mentioned configuration is adopted in which information is temporarily sucked up into a hard disk having a high data transfer rate.

Second, MD or C currently on the market
Most optical disc devices for D or CD-ROM or CD-R for external storage are SCSI,
Or, it has only a SCSI-like interface.

One of the causes that hinders direct transfer is the low transfer rate. Since it uses SCSI etc. for the interface, when transferring with the host computer,
This is because so-called overhead time such as confirmation of connection with the external storage device is required. Therefore, if a high-speed data transfer interface dedicated to information copying can be manufactured and arranged here, the information reading optical disk device 103 can be transferred to the information writing optical disk device 104 without performing such a two-step transfer procedure. It is possible to copy while transferring data directly.

Another cause is that the data transfer rate, that is, the disk rotation speed, does not exactly match between the information reading optical disk device 103 and the information writing optical disk device 104. For example, when the disc rotation speed of the information reading optical disc device 103 is slightly slower than that of the information writing optical disc device 104, the information writing optical disc device 1
In 04, the data accumulated inside is used up gradually and continuous recording becomes impossible. Further, when a defect such as a read error occurs during information reproduction in the optical disk device, it is common to read again, but when reaccess takes time, continuous recording cannot be continued. In this respect, hard disks are MD and CD
The access time is shorter than that of the CD-ROM and the CD-R, and the recovery time is short even if rereading is performed, which is advantageous and is used as shown in FIG.

As described above, the conventional optical disk device uses the SC
Since it has only the SI interface, there is another drawback in addition to the slow transfer rate as described above. Since the host computer 101 has a built-in SCSI driver which is a part of basic software for operating the SCSI interface circuit and inputting / outputting data from the software running on the host computer, the system shown in FIG. In the configuration, when information is transmitted via the SCSI interface incorporated in the host computer, the data on the master optical disc 106 which is the information source is stored in a logical format which can be recognized by the driver incorporated in the host computer 101. It has to be.

The logical format for storing data on an optical disk is not unified at present, and it differs depending on the type of host computer, the type of basic software, or the type of SCSI interface driver. When reading or writing an optical disc of each logical format, it is necessary to reconfigure the system configuration to suit each time, which is very inconvenient for the user.

Here, without depending on the interface with the host computer such as SCSI, or depending on the logical format when the information is recorded on the optical disk,
The inventors of the present application believe that it would be possible to construct a very convenient system if it could realize the function of simply reading the binary data on the master optical disc 106 and writing it on the duplication optical disc 107. Thought.

Now, a CD or a CD-RO having a copy function
One of the uses of the M optical disc device is considered for small-scale CD publishing. In such applications, it is required to make a copy of one master from 10 sheets to several tens of sheets in the shortest possible time. This is because, if a CD-ROM is manufactured with a small number of copies of this level, the cost of newly initiating the stamper is high, and when compared by unit price, the cost of recording on the CD-R is lower. The information storage device to which the present invention is applied is expected to have such uses, but no storage device or system for automatically copying a small number of sheets has been provided yet. Therefore, the inventors of the present application are desired to have a system that can make a designated number of copy discs after initial setting without the user having to replace the discs one by one. I thought there was no.

To help understand and explain the following parts,
The data modulation / demodulation / modulation / decoding paths in the CD-ROM and CD-R will be briefly described.

The formats of both discs are logically the same, and four types of formats are defined as shown in (a), (b), (c) and (d) of FIG. One sector is composed of 2352 information bytes. In each sector, 12-byte SYNC byte for sector synchronization indicating the sector start position and 4-byte H indicating the sector address are included.
The eader byte is attached. Regarding the other 2336 bytes, there are four types of (a) to (d) above.

FIG. 42A shows a MODE-of a CD-ROM.

User data is stored in the portion marked as ata.

In the formats shown in (a) and (c), an EDC byte for error detection and an ECC byte for error correction are added to reduce the data error rate. In the formats shown in (c) and (d), (a),
As not shown in (b), a Sub Header byte defined to indicate the type of data in each sector is added.

How the data of such a format is recorded on the optical disc will be described by taking a CD-R recording as an example. Optical disk device 104 from host computer 101 via interface 102
Which format of (a) to (d) the user data input to is in must be set in advance between the two. The input data is interpreted according to the format, and if it is (a) or (c), the EDC encoder 127 and the ECC encoder 1
At 26, an EDC byte and an ECC byte are added according to the data structure of the CD-ROM format. If (b) or (d), EDC encoder 12
7 and the ECC encoder 126 outputs the data without performing any operation. In the next SYNC addition circuit 125, the SYNC byte and the Header byte, and (c),
If the format (d) is used, Sub H
An eader byte is added.

In the next CIRC encoder 124, a cross interleave (CI) process for avoiding burst errors and a Reed-Solomon coding (RC) process are added. These two processes are collectively called CIRC coding. This is a process peculiar to a CD, and for each of the input data strings of any of (a) to (d), it is divided into 24 bytes in order from the beginning of the sector, and for each 24 bytes, (1) Specified interleaving in byte units, that is, changing the order of data, and (2)
Two types of processing, that is, addition of an error correction code of 8 bytes, are performed and output as a total of 32 bytes of data.

In addition to the CIRC-encoded data, a subcode is separately generated in the subcode generation circuit 128 at a ratio of 1 byte to the 32 bytes of data, and both are input to the EFM encoder 123 to be formatted. Are combined and EFM modulated. A sync bit pattern is added to 33 bytes of this input data at a rate of 27 channel bits, and EF
As a result of M modulation, a channel bit string of 588 channel bits is obtained. The unit of this 588 channel bit is EF
It is called M frame. The subcode generated by the subcode generation circuit 128 includes the CRC generation circuit 12
The CRC previously generated in 9 is added.

The channel bit string output from the EFM encoder 123 is pulse width modulated by the recording correction circuit 122 so as to have a pulse width suitable for recording, and the binary signal subjected to this recording correction is the LD control circuit. 1
Sent to 21. The output power of the laser diode (LD) in the optical head 109 is intensity-modulated by the LD control circuit 121, and a laser pulse for recording is output. The above is the general operation of the circuit during recording.

At the time of reproduction, the information on the optical disk is reproduced by following the above process exactly in reverse. Conventional CD-
In the optical disk device such as the ROM, as described above, all the information is input / output to / from the host computer 101 via the interface such as SCSI as the data after the CD-ROM format decoding.

Now, as can be easily inferred from each drawing of FIG. 42, even if the disc is of the (a) or (b) format, the sector thereof is (a) or (b) depending on the contents of the USER Data. Or Sub He
It may be unclear whether the disc is a (c) or (d) format disc having an ader byte. Because of this, when trying Suiageyo data contents once the host computer 101 according to the type of data in each sector, which leads to occurrence of a read error when no advance which format or Waka'i. In other words,
This means that even if all bit patterns on the disc can be reproduced, it is impossible to duplicate unless the format is known.

As can be seen from this description, the optical disk device 104 must perform encoding at the time of recording while determining which of the four types of formats shown in FIG. 42 the data coming from the host computer 101 is in. That is,
When an attempt is made to copy an optical disk, there is a limitation that both the host computer 101 and the optical disk device 104 must be able to handle the format, and even if the format of the optical disk to be used can be loaded. At present, it is very inconvenient to use as a device because the user has to manually perform the procedure of setting the type for each optical disc.

Example 3. FIG. 3 is a diagram showing a third embodiment of the information storage device according to claim 1 of the present invention. In the figure, the same symbols as those in FIG. 1 mean the same components. Reference numeral 7 is another information writing optical disk device, 31 is another information writing optical disk, and 32 is another information writing means.
When the information reading optical disc 11 and the information writing optical discs 21 and 31 are inserted, the information reading optical disc device 1 and the information writing optical disc devices 2 and 3 are in a readable state and a writable state, respectively. The states of the above are notified to each other by the control signal 4. After all the optical disk devices are in the readable and writable state, the information 3 read from the information reading means 12 starts to be transferred to the information writing means 22 and the information writing means 32. As a result, the information of one read disk is written on two write disks. Although two optical disk devices for writing information are connected in FIG. 3, three or more optical disk devices may be connected.

Example 4. FIG. 4 is a diagram showing a first embodiment of the information storage device according to claim 2 of the present invention. A CD-ROM is used as an optical disk for reading information, and a CD-Recordab is used as an optical disk 21 for writing information.
le disk shall be used. In the figure, 8 is a reference clock generating means, 9 and 10 are clock frequency dividing circuits,
13 is an EFM signal detection circuit, and 23 is a wobble frequency detection circuit. 14, 24 are spindle motor control circuits, 1
Reference numerals 5 and 25 are spindle motors for rotating the disks 11 and 21, respectively. Reference clock generating means 8
The reference clock generated from is divided by the frequency dividing circuit 9 and input to the circuit 13 for detecting the EFM signal written on the information reading optical disk 11, and the bit length of the detected EFM signal is predetermined. The spindle motor 1 is controlled through the spindle motor control circuit 14 so that the time becomes longer.
5 is controlled so that the information reading speed of the information reading optical disk 11 becomes constant.

In the information writing optical disk device 2, the reference clock generated by the reference clock generating means 8 is divided by the frequency dividing circuit 10 to detect the wobble signal written in the information writing optical disk 21. The spindle motor 25 is driven through the spindle motor control circuit 24 so that the frequency of the wobble signal input to the circuit 23 and detected becomes a predetermined value so that the information writing speed of the information writing optical disc 21 becomes constant. Controlled.

Although the frequency division ratios of the frequency dividing circuits 9 and 10 are different, since the reference clock before frequency division is common, for example, if the linear velocity of the information reading optical disk 11 is 1.2 m / s, The linear velocity of the writing optical disk 21 is also 1.2 m
/ S, and the information reading speed and the information writing speed are synchronized. That is, since the read and write speeds match, the buffer for storing the read information (data) may have a very small capacity.

The present embodiment has been described on the assumption that a CD-ROM disc is used, and the information reading optical disc 11 and the information writing optical disc 21 are used.
The rotational speeds of the respective spindle motors are controlled so that the linear velocity becomes constant, but when the OD is used, the spindle motors are controlled so that the rotational speed becomes constant.

Example 5. FIG. 5 is a diagram showing a second embodiment of the information storage device according to claim 2 of the present invention, and it is assumed that there are two information writing optical disk devices.
In the figure, 3a is an optical disk device for writing information different from 2b, 10a is a reference clock frequency dividing circuit, 31 is an optical disk for writing information, 33 is a wobble frequency detection circuit, 34 is a spindle motor control circuit, and 35 is a disk 31. It is a spindle motor for rotating. The other elements are the same as in FIG. The operation is the same as in FIG. 4, and the information read from the information reading optical disk 11 is written in the information writing optical disks 21 and 31. The frequency dividing circuit 10a may be shared with 10. Further, the reference clock generating means 8 and the frequency dividing circuits 9, 10, 10
A may be built in the information reading optical disk device 1 or the information writing optical disk devices 2 and 3. Also, the read / write optical disc is a MiniDisc.
But it is okay. Further, if the reading and writing optical disc is an OD, in order to control the writing speed,
It is not necessary to read out the information on the disc, and it suffices to control the number of revolutions of the disc to be constant.
3, 33 are unnecessary.

Example 6. FIG. 6 is a diagram showing an embodiment of an information storage device having a write information storage buffer corresponding to FIG. In FIG. 4 or FIG. 5, the reading position of the information reading optical disc 11 and the writing positions of the information writing optical discs 21 and 31 do not need to basically match, and there is a difference between the reading position and the writing position. It is necessary to store a corresponding amount of information (data amount) in the buffer. In the figure, 27 is an information writing optical disk device 2 and 37 is a writing information storage buffer used for the operation of the information writing optical disk device 3. The information read by the information reading means 12 of the information reading optical disc device 1 is temporarily stored in the buffer 27,
After being stored in 37, it is transferred to the information writing means 22 and 32 at a predetermined writing timing to write information.

Example 7. FIG. 7 is a diagram for explaining the temporal relationship between read information and write information. 4 or 5, the reading position of the information reading optical disk 11 and the writing positions of the information writing optical disks 21 and 31 need to be ahead of the information reading optical disk 11 by a predetermined amount. In the figure, the horizontal axis represents time, 16 is a set of information (data) read from the information reading optical disk device 1, and 26 and 36 are information (data written in the information writing optical disk devices 2 and 3, respectively. ) Is a set of. 16a, 16b,
Reference numeral 16c is a read data block, and write data blocks 26a, 26b, 26c and 36, respectively.
a, 36b, 36c are written on the information writing optical disks 21 and 31.

In FIG. 7, assuming that the time when the writing operation of the data 26a is started is time 0, it does not have to coincide with the timing of the writing start of the writing data 36a. However, the data 16a to be read must precede the write data 26a and 36a by a predetermined amount in time. For example, if the data 16 is data of a CD-ROM disc, the data 16a is EFM demodulated from the time when all the data 16a is read,
Further, demodulation based on the CD-ROM format is performed to restore the information (data) written on the information reading optical disk 11. If the restored data is transferred to the information writing optical disk devices 21 and 31, the data 16a must be read in advance for the time required for this demodulation. The amount of data read earlier by the time required for this demodulation is stored in the write information storage buffers 27 and 37.

Example 8. The fact that the read data must be read before the write data means that the read-side disk must rotate ahead of the write-side disk by a predetermined amount of rotation phase. . Therefore, it is necessary to detect this preceding amount. CD-ROM for reading information
In the case of a disk, the time for reading the read data 16 can be detected in units of 1/75 second by detecting the subcode after demodulating the data 16. Further, if an FM-modulated wobble signal is FM-demodulated from an information writing optical disc CD-Recordable disc, ATIP (Absolute Time in Pr) is obtained.
information can be obtained and time information of the information writing position can be known. If the information reading optical disc and the information writing optical disc are MDs,
ADIP (Address in Pregroov
e) By demodulating the information, the current read and write positions can be known. If the optical disc for reading information and the optical disc for writing information are OD, the present position of reading and writing can be known by demodulating the address information written on the disc.

Example 9. FIG. 8 is a diagram showing a first embodiment of the information storage device according to claim 3 of the present invention.
It is a figure explaining the timing of read-out information (data) transfer and information writing. In the figure, 18 is a CD information demodulating means, 19 is a CD-ROM information demodulating means, 20 is a data storage buffer after demodulation, 28 is a CD information modulating means,
29 is a CD-ROM information modulating means, 30 is a buffer for storing information before modulation, 40 is demodulation information (data) transfer means,
Reference numeral 41 is an information transfer reference clock generating means, and 42 is an information transfer reference clock. Other components having the same numbers as those in FIG. 1 are the same as those in FIG.

As an example, the information reading optical disk 1
1 is a CD-ROM disc. The information read from the information reading optical disk 11 is a CD
The information demodulating means 18 uses the EFM (Eight to Fo).
(Urteen Modulation) demodulation, error correction is performed, and C-ROM information demodulation means C
Data of a format based on the D-ROM format is demodulated, and only the original data that the host computer can recognize as a file is extracted and stored in the data storage buffer. The demodulated data transfer means 40 synchronizes the data read from the demodulated data storage buffer 20 with the information transfer reference clock 42, and stores the data storage buffer 3 before modulation.
Transfer to 0.

Further, in synchronization with the information transfer reference clock 42, the data in the data storage buffer 30 before modulation is transferred to the CD- by the information transfer means 40 such as DMA transfer.
It is transferred to the ROM information modulating means 29. The information modulated by the CD-ROM information modulating means 29 into the data format based on the CD-ROM format is transferred to the CD information modulating means 28 at the subsequent stage in synchronization with the information transfer reference clock 42, and the error correction code is sent. ECC is added and EFM modulated. The EFM-modulated information is written on the information writing optical disc 21. Normally, a CD-ROM has 20
Since 48 bytes are used as one information block unit, it is desirable that information is transferred and modulated in one information block unit in synchronization with the reference clock for information transfer.

In FIG. 8, since the transfer of the demodulated data to the data storage buffer 30 before modulation and the transfer to the data modulation means at the subsequent stage are synchronized, the capacity of the data storage buffer 30 before modulation is large. Even if the capacity is small, the data transfer is not interrupted and is correctly modulated by the data modulating means.

Example 10. FIG. 9 is a diagram showing a second embodiment of the information storage device according to the third aspect of the present invention, and is a diagram for explaining the timing of read information (data) transfer and information writing. Each component in the figure is the same as in FIG.

As an example, the information reading optical disk 1
1 is a CD-ROM disc. The information read from the information reading optical disk 11 is a CD
The information demodulating means 18 uses the EFM (Eight to Fo).
(Urteen Modulation) demodulation, error correction is performed, and C-ROM information demodulation means C
Data of a format based on the D-ROM format is demodulated, and only the original data that the host computer can recognize as a file is extracted and stored in the data storage buffer. The demodulated data transfer means 40 transfers the data read from the demodulated data storage buffer 20 to the pre-modulation data storage buffer 30. These series of operations are performed in synchronization with the information transfer reference clock 42.

Further, the data storage buffer 3 before modulation
The data in 0 is transferred to the CD-ROM information modulating means 29. The information modulated by the CD-ROM information modulating means 29 into a data format based on the CD-ROM format is
In synchronization with the information transfer reference clock 42, the data is transferred to the CD information modulating means 28 in the subsequent stage, and the error correction code ECC is added to the EFM modulation. The EFM-modulated information is written on the information writing optical disc 21. Normally, a CD-ROM has 2048 bytes as one information block unit, and therefore it is desirable that information is transferred and modulated in one information block unit in synchronization with a reference clock for information transfer.

In FIG. 9, since the demodulation of data, the data transfer to the data storage buffer 20 after demodulation, and the transfer to the data storage buffer 30 before modulation are synchronized, the data storage after demodulation is performed. Even if the buffer 20 has a small capacity, data transfer is not interrupted and the data is properly modulated by the data modulating means. CD information demodulating means 1
8, CD-ROM information demodulating means 19, demodulated data storage buffer 20, CD information modulating means 28, CD-RO
M information modulating means 29, buffer 3 for storing information before modulation
0, all modulation operations of the demodulation information (data) transfer means 40 and data transfer may be synchronized with the information transfer reference clock 42, but in that case, the information reading optical disk 11 and the information writing optical disk 21. It is necessary to match the rotation phase with the predetermined amount as well as the rotation synchronization.

Example 11. FIG. 10 is a diagram showing a first embodiment of the information storage device according to claim 4 of the present invention, which is, so to speak, a disc 11 in the information reading optical disc device 1.
FIG. 6 is an explanatory diagram related to the rotation and the rotation control operation of the disc 21 in the information writing optical disc device 2. In the figure, the components having the same reference numerals as those in FIG. 4 mean the same components. 8
Reference numeral a is a reference clock generating means of the information reading optical disk device 1, which is basically the same type as 8, but the oscillation frequencies may be shifted.

The operation of the information storage device in FIG. 10 is the same as that in FIG. 4, but since the information reading optical disk 11 and the information writing optical disk 21 are controlled in rotation based on different reference clocks, respectively. The linear velocity, that is, the information reading speed and the information writing speed are slightly different. When the information reading speed is faster than the information writing speed, if the capacity of the data storage buffer 20 after demodulation shown in FIG. 9 is insufficient, the data overflows from the buffer 20 and the information writing optical disk device. Data transfer is missed. On the contrary, when the information reading speed is slower than the information writing speed, the demodulated data storage buffer 20 in FIG. 9 becomes empty immediately, and the data transfer to the information writing optical disk device is interrupted. The information writing operation fails.

11 and 12 are diagrams for explaining the above-mentioned phenomenon, the horizontal axis represents time, and 16 represents the disk 11.
Read information from the disk 2 and 26 and 36 respectively.
1 and information written to the disk 31. 16
Reference numerals a, 16b, and 16c are one block of the read information 16, and 26a, 26b, 26c, 36a, 36b, and 36.
The same applies to c. FIG. 11 is a diagram for explaining the time relationship between read information and write information, and shows the case where the information read speed is slower than the information write speed.
FIG. 12 is an explanatory diagram of the opposite case.

11 and 12, the read information 16a is written on the disks 21 and 31 as 26a and 36a. Since the information reading speed is slower than the writing speed in FIG.
If the amount of read information is large even after starting to write 26 to 26a, it means that the write information 26 must be written before the time when the read information 16 has been read, and the information to be written is interrupted in the middle. become. In a disc such as a CD, the error correction information is interleaved before and after the writing time, so that the succeeding information cannot be written later and the writing operation ends up failing.

On the contrary, in FIG. 12, since the information reading speed is faster than the writing speed, the writing information 26 must be written for a while even after all the reading information 16 has been read. That is, it is necessary to store information that has been read out quickly in the buffer memory.

Therefore, for example, in FIG. 8, the capacity of the data storage buffer 30 before modulation is set to the total information on the disc based on the difference between the information reading speed of the information reading optical disk device and the information writing speed of the information writing optical disk device. Even if the information read speed and the information write speed are not synchronized, the buffer memory stores the read value in advance of writing the information by making the value more than twice the value multiplied by the write time. The write operation does not fail.

Even if the difference between the information reading speed and the information writing speed cannot be detected directly, the reference clock generating means 8
This can be estimated by taking into account the amount of deviation from the typical value of 8 and 8a. The deviation from the typical value may be variation in the oscillation frequency due to individual variation or temperature change. For example, if the oscillation frequency of the reference clock generation means 8 is
22MHz plus or minus 0.01%, same as 8
Oscillation frequency of a is 33MHz plus or minus 0.01%
Then, the difference between the information reading speed and the information writing speed is plus or minus 0.02%.
The standard value of information read speed and information write speed is 150
kB / s, and if the total write time of the disk is 74 minutes, 150 kB / s × 74 × 60 s × 0.02% × 2
= A buffer of 266.4 kB or more may be provided.
The buffer memory is an optical disk device 1 for reading information.
The data storage buffer 20 after demodulation may be used.

Example 12. By starting the writing of information by the writing optical disc device after the amount of information read from the reading optical disc device has accumulated about half or more of the memory capacity of the buffer memory, FIG.
Also in the case shown in FIG. 12 and FIG. 12, information writing is successful. That is, when the reading speed is faster, the data is gradually accumulated in the buffer even after the writing is started, and the amount of data accumulated in the buffer from the start to the end of the writing is the difference between the reading speed and the writing speed. Is multiplied by the total information writing time to the disc. If the buffer capacity is at least twice the amount of data accumulated from the start to the end of writing, the data can be correctly written to the end without the data overflowing from the buffer.

On the contrary, even when the read speed is slower, the write operation is started after more than half the data of the buffer capacity is accumulated, so the data in the buffer gradually decreases from the start to the end of the write. , Since the amount of data that is decreased from the start of writing to the end is stored in the buffer in advance, the write operation is started.
The buffer is not empty, and data can be written correctly to the end.

Example 13. FIG. 13 is a diagram showing a first embodiment for realizing claim 6. The range shown in the information storage device according to the present invention in the figure is the information copying system 150 included in this embodiment. Further, the range shown in the information storage device according to the present invention with the portion 155 deleted according to the present invention added thereto is included in the conventional example.

In the present embodiment, the information to be copied is read by the information reading optical disk device 153 on the information source optical disk 106, converted into a significant binary data string, and then the information is directly recorded on the copying optical disk. It is transferred to the optical disk device 154 on the recording side. In the conventional example, the binary data string is sent to the interface (SCSI) of the host computer 101, where the decoding process 151 of the logical format for data reading is first performed.
, And once recognized as information by the host computer, the information is again encoded in a logical format 1
It is multiplied by 52 and sent to the writing circuit.

Therefore, by constructing as in the present embodiment, the entire system for copying can be simplified, and since the recognition of the logical format becomes unnecessary at the time of transfer, it is easy to perform regardless of the format. Moreover, the feature that it can be duplicated at high speed comes out.

Example 14. FIG. 14 is a diagram showing a second embodiment for realizing claim 6. This system comprises an information reading optical disk device 153, an information writing optical disk device 154, a master optical disk 106 and a duplication optical disk 107. In this embodiment, as in the case of the thirteenth embodiment, the information to be copied is read by the information reading optical disk device 153 on the information source optical disk 106, converted into a significant binary data string, and then copied as it is. The information is transferred to the optical disk device 154 that records information on the optical disk 107.

Generally, in the optical disk device, as shown in FIG.
The binary data string at the time of reading information is first demodulated with a recording modulation code and then decoded with an error correction code, as shown in FIG. The error correction coding is not limited to once, but may be subjected to a plurality of stages of error correction coding in order to improve data reliability. Further, the information may be modified or organized according to a particular sector logical format, in which case the sector logical format is decrypted.

As the binary data string to be transferred, it is possible to select a binary data string at any stage in the decoding process of the error correcting code in the plurality of stages. In the present embodiment shown in FIG. 14, the binary data string at the time when the first-stage error correction decoding is performed on the read information of the optical disc that has been subjected to the two-stage error correction coding is transferred as the information to be duplicated. An example is shown. Here, for general description, different recording modulation codes are used on the master optical disc side and the duplicate optical disc side, and an example in which the number of error correction stages is also different is shown. That is, the read data is first demodulated by the demodulator 131 of the first recording modulation code, and then the first-stage error correction is performed by the decoder 132 of the first error correction code. This decoded binary data string is transferred. In order to obtain the information 135 normally reproduced up to the final stage, the sector logical format decoder 134 further decodes the data format, and the decoder 133 of the second error correction code performs the second stage error correction. There is a need.

In the writing optical disc device 154 to which the information has been transferred, if necessary, error correction coding suitable for the duplication optical disc is performed again, or after modulation by the recording modulation code, the duplication optical disc is applied. It is recorded in 107. In this embodiment, the information writing optical disk device 154 does not perform error correction coding, but immediately performs recording modulation by the modulator 136 of the second recording modulation code and records it on the optical disk 107. Information can be duplicated even between optical disk devices that use different recording modulation code and error correction code configurations. Needless to say, the code configuration is not limited to that shown in this embodiment.

By configuring as in this embodiment,
The entire system for copying can be simplified, and since the recognition of the logical format becomes unnecessary during transfer, it has the advantage that it can be copied easily and at high speed regardless of the format.

Example 15. FIG. 15 is a diagram showing a third embodiment for realizing claim 6. This system comprises an information reading optical disk device 153, an information writing optical disk device 154, a master optical disk 106 and a duplication optical disk 107. In the present embodiment as well, as in the fourteenth embodiment, the information to be copied is read by the information reading optical disk device 153 on the information source optical disk 106 and converted into a significant binary data string, and then copied as it is. The information is transferred to the optical disk device 154 that records information on the optical disk 107.

The difference from the fourteenth embodiment is that
The point is that the binary data string at the time when the second-stage error correction decoding is performed on the read information of the optical disc that has been subjected to the two-stage error correction encoding is transferred as the information to be duplicated. The read data is first demodulated by the demodulator 131 of the first recording modulation code, and then the first stage error correction is performed by the decoder 132 of the first error correction code. Further, the sector logical format decoder 134 decodes the format, and the second error correction code decoder 133 performs the second stage error correction. The binary data string thus decoded is transferred as the reproduction information 135.

In the writing optical disk device 154 to which the reproduction information 135 has been transferred, first the second error correction coding is applied through the encoder 137 of the second error correction code,
Information is then formatted through the sector logical format encoder 138. After that, the second recording modulation is applied by the modulator 136 of the second recording modulation code and recorded on the duplication optical disc 107. Information can be duplicated even between optical disk devices that use different recording modulation code and error correction code configurations. Needless to say, the code configuration is not limited to that shown in this embodiment.

By configuring as in this embodiment,
The entire system for copying can be simplified, and since the recognition of the logical format becomes unnecessary during transfer, it has the advantage that it can be copied easily and at high speed regardless of the format.

Example 16. FIG. 16 is a diagram showing a first embodiment for realizing claim 7, and shows an optical disk duplication system 160 in the present invention. This system comprises an information reading optical disk device 163, an information writing optical disk device 164, a master optical disk 106 and a duplication optical disk 107.

The reproduction light waveform read from the master optical disk 106 by the information reading optical disk device 163 is taken out as an optical detector output signal by the optical head 109. This is amplified by the head amplifier 111 and used as a reproduction RF signal. The data separator 112 binarizes the reproduced RF signal, which is an analog signal waveform, by an appropriate circuit generally used in a CD-ROM drive or the like, and further synchronously detects the reproduced RF signal with a reproduced clock signal. The reproduced clock signal itself is generated by a phase lock loop circuit (PLL) built in the data separator 112. The data separator output signal thus obtained is a signal that is still subjected to EFM modulation.

This EFM-modulated signal is transferred to the information writing optical disc device 164 as it is together with the reproduction clock signal without being demodulated. In the information writing optical disc device 164, the EFM modulation signal and the reproduction clock signal are input to the recording correction circuit 122. Hereinafter, the recording correction circuit 122 applies pulse width modulation to the duplication optical disk 10.
The process of recording data in No. 7 is the same as the process in the conventional writing optical disc device 104.

That is, in this embodiment, in the information writing optical disk device 164, the EF of the conventional example is used.
By using the EFM modulation signal and the reproduction clock signal sent from the information reading optical disk device 163 instead of the signal from the M encoder 123, the EF
At the M modulation signal level, the information from the information source side is passed to the duplication side. By doing so, it is possible to copy regardless of which CD-ROM format shown in FIG. 42 the handled optical disk has, without the user having to specify the format each time.

Since the CD-R is taken as an example in the present embodiment, EFM modulation is used as the recording modulation code, but it is not limited to EFM modulation depending on the type of information reproducing apparatus or information recording apparatus. As another example, when ODD is used in an information recording optical disk device disk device, the recording modulation code is (2-7) RLL.
A code or a (1-7) RLL code is used. Even in this case, the transfer information is still the channel bit string before demodulating these recording modulation codes.

Example 17 FIG. 17 is a diagram showing a second embodiment for realizing claim 7, and shows an optical disk duplication system 170 in the present invention. It differs from the sixteenth embodiment shown in FIG. 16 in that an interface for connecting to the host computer 101 is provided. The system to which the present invention is applied may be a normal CD-RO in some cases.
As in the case of M reproduction, it is sometimes desired to confirm the contents with the host computer 101 and then use the optical disk for copying. In order to respond to such uses,
As shown in this embodiment, in addition to the information transfer line shown in the fourteenth embodiment, a host computer interface is provided like the conventional optical disk device for CD-ROM.

When copying an optical disk with this system, the EFM modulated signal is transferred as in the fourteenth embodiment. In the present embodiment, in the information writing optical disc device 174, E is input to the input unit of the recording correction circuit 122.
A selector for selectively inputting either the EFM modulated signal from the FM encoder 123 or the EFM modulated signal from the information reading optical disk device 173 is added.

The command signal for switching the selector is a switch operation by the user or the host computer 10
According to the control signal from 1.

Example 18. FIG. 18 is a diagram showing a third embodiment for realizing claim 7, and shows an optical disk duplication system 165 in the present invention. This system comprises an information reading optical disk device 168, an information writing optical disk device 169, and a master optical disk 106 and a duplication optical disk 107. The difference from the sixteenth embodiment is that the recording modulation code is not EFM modulation but (2-
7) It uses the RLL code.

The reproduction light waveform read from the master optical disk 106 by the information reading optical disk device 168 is taken out by the optical head 109 as a photodetector output signal. This is amplified by the head amplifier 111 and used as a reproduction RF signal. The data separator 112 binarizes the reproduced RF signal, which is an analog signal waveform, by an appropriate circuit generally used in an optical disk device, and further synchronously detects the reproduced RF signal with a reproduced clock signal. The reproduced clock signal itself is generated by a phase lock loop circuit (PLL) built in the data separator 112. The data separator output signal thus obtained is a signal that is still subjected to (2-7) modulation, that is, a channel bit string before demodulating the recording modulation code.

The (2-7) modulated signal is directly transferred to the information writing optical disk device 169 together with the reproduction clock signal without being demodulated. In the information writing optical disk device 169, the (2-7) modulated signal and the reproduction clock signal are input to the recording correction circuit 122. Less than,
The process of applying pulse width modulation by the recording correction circuit 122 and recording on the duplication optical disc 107 is the same as the process in the conventional writing optical disc device 104.

That is, in this embodiment, in the information writing optical disk device 169, instead of the signal from the encoder 146 of the (2-7) modulation code,
It is sent from the information reading optical disk device 168 (2
-7) By using the modulation signal and the reproduction clock signal, the information from the information source side is passed to the duplication side at the recording modulation signal level. This makes it possible to copy regardless of the logical format of the optical disc being handled.

Example 19. FIG. 19 is a diagram showing a first embodiment for realizing claim 8, and shows an optical disk duplication system 180 in the present invention. This system comprises an information reading optical disk device 183, an information writing optical disk device 184, and a master optical disk 106 and a duplication optical disk 107.

In this embodiment, the EFM modulated signal obtained by the optical disk device on the information reading side of the sixteenth embodiment is further EFM demodulated and then transferred to the optical disk device on the information writing side. That is, the transferred data becomes a binary signal that is still subjected to the CIRC modulation immediately after demodulating the EFM signal.

Explaining in the block diagram, the EFM demodulated signal output from the EFM decoder 113 of the information reading side optical disc device 183 is directly transferred to the information writing optical disc device 184. In the information writing optical disk device 184, the EFM demodulated signal is input to the EFM encoder 123. Hereinafter, the EFM encoder 123
The EFM modulation is performed by the method, the pulse width modulation is performed by the recording correction circuit 122, and the data is recorded on the duplication optical disc 107, as in the processing in the conventional writing optical disc device 104.

That is, in this embodiment, in the information writing optical disk device 184, information is read from the CIRC encoder 124 and the CIRC encoded signal from the sub code generation circuit 128 at the input portion of the EFM encoder 123, instead of reading information. Optical disk device 18
By using the EFM demodulated signal sent from
At the EFM demodulation signal level, the information from the information source side is passed to the duplication side. By doing so, it is possible to copy regardless of which CD-ROM format shown in FIG. 42 the handled optical disk has, without the user having to specify the format each time.

Since CD-R is also taken as an example in this embodiment, EFM modulation is used as the recording modulation code, but it is not limited to EFM modulation depending on the type of information reproducing apparatus or information recording apparatus. As another example, when ODD is used in an information recording optical disk device disk device, the recording modulation code is (2-7) RLL.
A code or a (1-7) RLL code is used. Even in this case, the transfer information is still the binary data string immediately after demodulating these recording modulation codes.

Example 20. FIG. 20 shows the second embodiment for realizing claim 8 and shows an optical disk duplication system 190 according to the present invention. It differs from the nineteenth embodiment shown in FIG. 19 in that an interface for connecting to the host computer 101 is provided. The system to which the present invention is applied may be a normal CD-RO in some cases.
As in the case of M reproduction, it is sometimes desired to confirm the contents with the host computer 101 and then use the optical disk for copying. In order to respond to such uses,
As shown in the present embodiment, in addition to the information transfer line shown in the nineteenth embodiment, a host computer interface is provided as in the conventional optical disk device for CD-ROM.

When copying an optical disk with this system, the EFM demodulated signal is transferred as in the nineteenth embodiment. In the present embodiment, in the information writing optical disk device 194, the CIRC encoder 124 and the CIRC encoded signal from the sub-code generation circuit 128 are input to the EFM encoder 123 or the EFM from the information reading optical disk device 193. A selector for selecting and inputting either the modulated signal is added.

The command signal for switching the selector is a switch operation by the user or the host computer 10.
According to the control signal from 1.

Since CD-R is taken up as an example in this embodiment, EFM modulation is used as the recording modulation code, but it is not limited to EFM modulation depending on the type of information reproducing apparatus or information recording apparatus. As another example, when ODD is used in an information recording optical disk device disk device, the recording modulation code is (2-7) RLL.
A code or a (1-7) RLL code is used. Even in this case, the transfer information is still the binary data string immediately after demodulating these recording modulation codes.

Example 21. FIG. 21 is a diagram showing a third embodiment for realizing claim 8 and shows an optical disk duplication system 185 in the present invention. This system comprises an information reading optical disk device 188, an information writing optical disk device 189, a master optical disk 106 and a duplication optical disk 107.

The difference from the nineteenth embodiment is that the information writing optical disk device 189 is ISO-10089.
An optical disk device that drives an optical disk of the standard, ISO-10090 standard, ECMA-183 standard, ECMA-184 standard, ECMA-195 standard, or the like. In this case, the recording modulation code on the side of the optical disk for information writing is not the EFM modulation code but the
The (2-7) RLL code (however, in the ECMA-195 standard, the (1-7) RLL code) is used. Even in this case,
Immediately after the transfer information demodulates the recording modulation code on the read side,
That is, the binary data string immediately before recording and modulation on the writing side remains unchanged.

In this embodiment, the EFM obtained by the optical disk device on the information reading side is the same as in the nineteenth embodiment.
The binary signal that has been subjected to the CIRC modulation immediately after demodulating the signal is transferred to the information writing side optical disc device.

Explaining in the block diagram, the EFM demodulated signal output from the EFM decoder 113 of the information reading side optical disc device 188 is directly transferred to the information writing optical disc device 189. In the information writing optical disk device 189, the EFM demodulated signal is input to the encoder 146 of the (2-7) modulation code. Below, (2-
7) (2-7) modulation is performed by the encoder 146, pulse width modulation is performed by the recording correction circuit 122, and the duplication optical disc 10 is performed.
7 is a conventional writing optical disc device 10
It is similar to the process in 4.

That is, in this embodiment, in the information writing optical disk device 189, the EFM demodulated signal sent from the information reading optical disk device 188 is input to the input section of the (2-7) encoder 146, so that the EFM demodulation signal is input. At the demodulation signal level, the information from the information source side is passed to the duplication side. By doing so, it is possible to copy regardless of which CD-ROM format shown in FIG. 42 the handled optical disk has, without the user having to specify the format each time.

In this embodiment, since the CD-R is taken as an example of the information reading optical disk device, it is called an EFM demodulation level signal as a transfer signal for copying, but if it is generally expressed. For example, this signal will be called a "signal immediately before recording modulation".

Further, although not shown, as another embodiment, the information reading optical disk device 188 also has an ISO
-10089 standard, ISO-10090 standard, ECMA
-183 standard, ECMA-184 standard, ECMA-19
A system using an optical disk device that drives an optical disk of 5 standards or the like is also possible. In this case, as the recording modulation code on both the information reading side and the information writing side,
The (2-7) RLL code (however, in the ECMA-195 standard, the (1-7) RLL code) is used. Even in this case, the transfer information is immediately after demodulating these recording modulation codes,
There is no change in the binary data string immediately before recording and modulation.

As described above, information can be duplicated between optical disk devices that use different recording modulation codes. In the description of the present embodiment, the EFM modulation code, the (2-7) RLL code, and the (1-7) RLL code are illustrated as specific examples as the recording modulation code, but the recording modulation code is, of course, the one shown in the present embodiment. It goes without saying that it is not limited.

Example 22. FIG. 22 is a diagram showing a first embodiment for realizing claim 9 and shows an optical disc duplicating system according to the present invention. This system comprises an information reading optical disk device 203, an information writing optical disk device 204, a master optical disk 106 and a duplication optical disk 107.

In the present embodiment, the EFM demodulated signal obtained by the read side optical disk apparatus in the above Example 19 is further subjected to error correction processing, and a signal having no error is transferred to the information writing side optical disk apparatus. To do.
The error correction process is processed as the following two types of data.

The first data is data to which the CIRC correction code is added, and the second data is data called subcode in the CD format. The subcode data has 98 bytes in one block, and the CRCC error detection code is added thereto, and a decoding process different from the CIRC code process is performed.

Explaining in the block diagram, the CIRC decode signal output from the CIRC decoder 114 of the information reading side optical disk device 203 and the subcode decoded by the subcode decoder 118 and further subjected to error detection processing by the CRC decoder. Are transferred to the information writing optical disk device 204.

In the information writing optical disk device 204, the data is re-encoded by the CIRC encoder 124, the subcode is processed by the CRC encoder 129 and the subcode encoder 128, and the two types of data are combined again to comply with the CD format. The resulting data is EFM-modulated by the EFM encoder 123.

The subsequent processing is the same as the processing in the conventional writing optical disk device 104. The sync signal within one frame specified by the CD format is EFM.
Addition processing is performed before modulation. That is, in this embodiment, in the information writing optical disk device 204,
The error-corrected data after EFM decoding is passed to the duplication side. Therefore, it is possible to copy the data without various problems on the host interface and without any error in the recorded data.

Example 23. FIG. 23 is a diagram showing a second embodiment for realizing claim 9. It differs from the embodiment shown in FIG. 22 in that an interface for connecting to the host computer 101 is provided. In some cases, the system to which the present invention is applied may be used such that the optical disk is copied after confirming the contents by the host computer 101 as in the case of normal CD-ROM reproduction. For this purpose, as shown in the present embodiment, in addition to the information transfer line shown in the twenty-second embodiment, a host computer interface is provided like the conventional CD-ROM optical disk device.

When an optical disk is copied by this system, the CIRC decode signal and the subcode CRC decode signal are transferred as in the twenty-second embodiment. In the present embodiment, in the information writing optical disc device 202, the CIR is provided in the input section of the CIRC encoder 124.
Either the signal from the C decoder 114 or the output signal of the encoders 127, 126, and 126 which perform various data format processing in FIG. 42 in the recording device is selected and input.

The method of selecting the signal is performed by using a switch of the user or a selector operated by a command from the host computer 101.

These ODDs are functionally capable of recording / reproducing and can be used in place of the CD-R device used in the main description example of the present invention. The main difference between the writing optical disk device 213 and the CD-R device in the block is the disk diameter, the modulation / demodulation method, the error correction code, and the disk format related to these. The disk capacity is larger or smaller than the CD depending on the type of various ODDs.
