[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording / reproducing apparatus for recording / reproducing information on / from an exchangeable recording medium such as a magneto-optical disc, a phase change type optical disc, etc. The present invention relates to an information recording / reproducing apparatus for copying onto a plurality of other media.

[0002]

2. Description of the Related Art Conventionally, in a small computer or the like, a floppy disk or the like has been widely used as a replaceable information recording medium which can be exchanged and carried around. Further, recently, as an information recording medium capable of recording a large amount of data such as image data, an optical exchangeable recording medium such as a magneto-optical disc or a phase change type optical disc has been used.

In such an exchangeable recording medium, it is possible to obtain a medium on which the same information is recorded from the original medium (master) by copying all information on the medium. . For example, when distributing information content, copying from a master medium to a plurality of media is performed.

In a recording / reproducing apparatus using a magneto-optical disk or a floppy disk, the information recorded on the master disk is copied to a plurality of disks so that a plurality of disks having the same information content can be simultaneously produced. Various medium copying apparatuses have been proposed.

The applicant of the present application, in Japanese Patent Application No. 6-121565, mounted a master medium on a master medium reproducing means as an information recording / reproducing apparatus for copying information recorded on a master medium to a plurality of copy destination media. It has been proposed to provide a copy control means for detecting such a situation and starting the copy process by mounting the master medium. According to this device, the copying process can be easily started only by inserting the medium into the device, and the information can be copied to a plurality of media by a simple operation.

In such an information recording / reproducing apparatus using a magneto-optical disk as a medium, for example, a plurality of copy destination disks are mounted in a copy destination disk drive unit serving as copy destination medium recording means, and then a master disk is mounted. Then, the copying process is started by mounting the disc into a master disc drive unit which serves as a master medium reproducing unit. At this time, the copy control means detects the insertion state of the master disk and the copy destination disk, and turns off the display LED corresponding to the copy destination disk drive unit in which the copy destination disk is mounted.
It is in a standby state until the master disk is mounted in the master disk drive unit. If the master disk or the copy destination disk is inserted in the drive unit before the power is turned on, the medium is ejected from the disk drive unit. Then, the copy control means detects the occurrence of an abnormality during the copy process, and when the copy process is completed, the master and copy destination disks for which the copy process has been completed normally are ejected from the disk drive unit, and the abnormality occurs during the copy process. The existing media will not be ejected from the disk drive unit.

[0007]

The above-mentioned Japanese Patent Application No. 6-1
In the device No. 21565, when starting the copy process,
The copy control means detects that the copy destination disk has been inserted into the copy destination drive unit, turns off the display LED corresponding to the disk drive unit in which the medium is mounted, and puts it in a standby state. With this functional configuration, the following problems occur.

1. Even if an abnormality occurs in the disk drive unit, such as the destruction of the semiconductor laser in the disk drive unit or disconnection of the spindle motor,
The permission signal may be sent to the upper copy control means, and the copy process may start. In this case, there is a problem in that the copy is ended without recording the data on the copy destination disk, and the copy destination disk that has not been normally copied is ejected from the disk drive unit as a copied disk.

2. Initialization in the copy destination disk drive unit compared to the time from when the master disk is inserted into the master disk drive unit to start the copy process and when the information written on the master disk is read and sent to the copy control means. If the preparation time for writing information such as processing is long, there is a problem that the actual copy start time is delayed.

3. When using a disk drive unit that can use a double-density disk or the like whose recording capacity has been increased by high-density recording as a medium, if a non-dense disk is inserted in the copy destination disk drive unit or the master disk is a non-dense disk If there is, will it be recorded twice as densely on the copy destination disc?
There is a problem that it is not possible to perform proper copy processing because it is not possible to determine whether or not to record at a normal recording density.

The present invention has been made in view of these circumstances, and an object thereof is to provide an information recording / reproducing apparatus capable of efficiently performing appropriate copy processing.

The buffer memory 6 is composed of, for example, a semiconductor memory having a capacity of 2 MB in consideration of the time efficiency at the time of copy processing, and temporarily stores a part of the data read from the master disk 21. ing. The apparatus of this embodiment has a structure having two SCSI buses so as to improve the drive operation rate in order to speed up the copy process. The number of SCSI buses is not limited to two, and may be appropriately increased or decreased according to the number of disk drive units to be arranged.

Next, the operation of the copying process for simultaneously copying the data of the master disk to a plurality of copy destination disks in the information recording / reproducing apparatus of this embodiment will be described. Here, the operation up to the start of the copy process will be described in detail with reference to the flowchart of FIG.

When performing copying, the user first performs step S1 (steps will be omitted hereinafter and is simply described as S1), and the required number of copy destination disks are the disk drive units 1b and 1c for copy destinations. Insert the disc into the drive and set the copy destination disc. CP
In S2, the U5 detects the disk insertion state in the copy destination disk drive units 1b and 1c, and if the copy destination disk is not inserted, returns to S1 and waits until the disk is inserted. If the master disc or the copy destination disc is inserted before the power is turned on, the disc is ejected from the corresponding disc drive unit.

In S2, the insertion of the copy destination disk is detected, and the disk drive units 1b and 1c for the copy destination are detected.
When the disc is loaded in the disc, the process proceeds to S3, in which the disc drive unit for each copy destination is initialized. This initialization processing is performed under the control of the drive controller 10 of the disk drive unit.

In the initialization process, first, when the drive controller 10 detects the completion of disk loading, it outputs a motor-on signal to the motor controller 13 to activate the spindle motor 11. Spindle motor 11
Is the preset rotation speed (eg 4200 rpm)
It is started up to the predetermined rotation speed of 4200r
When pm is reached, a constant speed control start signal is output from the motor controller 13 to the drive controller 10, and thereafter, constant speed control is performed at the predetermined rotation speed.

Next, the drive controller 10 sends a voice coil motor control signal to the motor controller 13 to drive a voice coil motor (not shown) of the optical head 12. As a result, the optical head 12 is moved in the inner circumferential direction of the copy destination disk 22 by the voice coil motor.

After that, the drive controller 10 outputs a control signal to the light emission / focus control section 15 to adjust the light emission of the semiconductor laser (not shown) in the optical head 12. For this semiconductor laser emission adjustment, the drive controller 10 is set with respective emission amounts at the time of reproduction, recording and erasing, which are predetermined corresponding to the copy destination disc used in the disc drive unit. The light emission / focus control unit 15 receives the light emission amount data for each access from the drive controller 10 and drives the semiconductor laser of the optical head 12 to emit light.
Each light emission amount is controlled by an APC circuit provided inside. Then, the value of the light emission amount corrected by the light emission amount control is sent to the drive controller 10 to be set, and thereafter, the light emission amount control is performed with this light emission amount value.

Further, the drive controller 10 emits light /
The control signal is output to the focus control unit 15, and the optical head 1
Adjust the focus servo of 2. When the drive controller 10 gives a start signal, the light emission / focus control unit 15 moves the objective lens of the optical head 12 within a predetermined search range to perform a focus search.
When the focus error signal becomes minimum, the search operation is stopped, the focus servo is turned on, and the focus control is started.

Subsequently, the SFP detection unit 14 detects the SFP in the control track provided on the inner circumference of the copy destination disk, and the drive controller 10 inputs the control track signal (SFP data) from the SFP detection unit 14. Then, the medium information of the copy destination disk that has been mounted is detected. A control track is formed on the inner and outer circumferences of the copy destination disc. The control track has a disc format format, modulation format,
Medium information such as the number of bytes of user data in one sector is recorded. The drive controller 10 uses a control track SFP or PEP (Phase Encode P
art) is scanned and reproduced by the light beam emitted from the optical head 12 to detect the medium information,
5 This makes it possible to identify the disk specifications such as whether the copy destination disk is a normal recording density disk or a double-density or triple-density disk.

With the above, the initialization processing in the copy destination disk drive units 1b and 1c is completed, and the drive controller 10 sets its own disk drive unit to the ready state in which it can read / write. The initialization process is independently performed in parallel in each of the copy destination disk drive units 1b and 1c.

At this time, the CPU 5 determines in S4 whether or not the copy destination disk drive units 1b and 1c are in the ready state, and waits until the ready state is reached. Then, in S5, the CPU 5 outputs a control signal to the display operation panel 9, and the recording capacity of the copy destination disk (capacity display such as normal recording capacity / double recording density)
The disc information identified as above is displayed on the display operation panel 9. In this state, the CPU 5 makes the copy destination disk drive units 1b and 1c stand by in a ready state.

When the copy destination disk is inserted, the write protect slide switch as a write protection mechanism provided in the disk cartridge is turned off to prevent write protection. If there is an error in inserting the copy destination disk, such as when the copy destination disk is write-protected, an error is displayed on the display operation panel 9. Thereby, the user visually recognizes the abnormal display on the display section of the display operation panel 9, recognizes the insertion error of the copy destination disk, and operates one of the corresponding eject buttons of the copy destination disk drive units 1b and 1c. It is also possible to eject the copy destination disk. Alternatively, the copy destination disk having the error may be automatically ejected.

Next, in S6, the user inserts the master disk into the master disk drive unit 1a to set the master disk in the drive. In S7, the CPU 5 detects the disc insertion state in the master disc drive unit 1a, and when the master disc is not inserted, returns to S6 and waits until the disc is inserted.

When the insertion of the copy destination disk is detected in S7 and the disk is loaded in the master disk drive unit 1a, the process proceeds to S8, in which the master disk drive unit is initialized.

The initialization process in the master disk drive unit is performed by the drive controller 10 of the master disk drive unit 1a.
After the completion of disk loading is detected, motor control processing and the like are performed as in the case of the copy destination. In this initialization process, the SFP in the control track of the master disc is detected to detect the medium information, and the disc specifications such as the recording capacity of the master disc are identified. Disk drive unit 1 for master
When the initialization process in a is completed, the drive controller 10 reads / writes its own disk drive unit.
It is ready for writing.

When the master or copy destination disk is not completely removed from the information recording / reproducing apparatus in the above initialization processing of the copy destination and master disk drive units (when the same disk as the previous one is mounted), A memory (not shown) in which the SFP data is stored is read out to be in a ready state. Alternatively, when each disc is inserted again and only the CAV or ZCAV disc system is different, the same processing as described above is performed. By omitting a part of the initialization processing in this way, it is possible to eliminate unnecessary processing time.

At this time, the CPU 5 determines in S9 whether or not the master disk drive unit 1a is in the ready state, and waits until it is in the ready state. Then, the CPU 5 makes the master disk drive unit 1a stand by in a ready state. At this time, the disc information such as the recording capacity of the master disc may be displayed on the display operation panel 9 in the same manner as the copy destination disc.

Subsequently, in S10, the CPU 5 compares the recording capacity of the master disk with the recording capacity of the copy destination disk, and when the capacity of the copy source master disk is larger than the capacity of the copy destination disk (when NG). Is S11
Then, an error message is displayed on the display / operation panel 9 and the master disk and the copy destination disk corresponding to the error are ejected. After that, it is determined whether or not the disc ejected in S12 is the copy destination disc. If the disc is the copy destination disc, the process returns to S1, and if it is the master disc, S6.
Return to

When the master disk is inserted, a write protect slide switch as a write protection mechanism provided in the disk cartridge is turned on to write protect the disk. If there is an error in inserting the master disk, such as when the master disk is not write-protected, an error display is displayed on the display operation panel 9. As a result, the user can visually check the abnormal display on the display section of the display operation panel 9, recognize an insertion error of the master disk, operate the eject button of the master disk drive unit 1a, and eject the master disk. It will be possible. Alternatively, the erroneous master disk may be automatically ejected.

In S10, when the recording capacity of the master disk and the recording capacity of the copy destination disk match, or when the recording capacity of the copy destination disk is larger than the recording capacity of the master disk, the copy source and copy at the time of performing the copy process If there is no abnormality in the previous disk capacity, S1
In 3, the CPU 5 determines whether both the master and copy destination disk drive units are in the ready state, and when both stand by in the ready state, the process proceeds to S14 to start the copy process.

That is, the user selects the copy destination disk (1
(More than one sheet) is inserted into the copy destination disk drive unit, and then the master disk is inserted into the master disk drive unit to start the copying process. At this time, the CPU 5 initializes each disk drive unit. The control track information (SFP information) from the master disk and the copy destination disk obtained in this initialization processing is detected to identify the specifications of both disks, and when performing the copy processing, the disk recording capacity etc. is determined. After recognizing that there is no abnormality and detecting that each disk drive unit is waiting in a ready state, the copy process is started.

In the copying process, first, the eject buttons of all the disk drive units 1a to 1c are locked to prevent erroneous ejection of the disks during the copying process. After that, the data on the entire surface of the master disk is copied to the copy destination disk.

The CPU 5 sends a command to the master disk drive unit 1a to read a predetermined amount of block data out of all data of the master disk from the master disk 21, transfer it via the SCSI bus 3a, and transfer it to the buffer memory 6. Read. Then, a command is sent to the copy destination disk drive units 1b and 1c to transfer the data in the buffer memory 6 to the SCSI bus 3a,
3b to write the data on the copy destination disk 22. Then, the data copy operation is repeated until the copying of all the data of the master disk to the copy destination disk is completed. At this time, a control signal is sent to the display / operation panel 9 to display the progress of the copying process on the display unit of the display / operation panel 9 in% or the like.

When an error occurs during the copy operation, the error is displayed on the display / operation panel 9 and the master or copy destination disk drive unit having the error is removed from the processing, and the copy processing cannot be continued. If not, the copy process is stopped.

When the copying of all the data is completed, the eject buttons of all the disk drive units 1a to 1c are unlocked, and no error occurs during the copying operation of the master and copy destination disk drive units 1a to 1c. Send a command to the drive to automatically eject only the master and copy destination disks for which copying has completed normally, and not the discs that have errors. At this time, the user recognizes the error at the time of copying the disk by the error display on the display operation panel 9, and presses the eject button of the disk drive unit to eject the master or the copy destination disk in which the error occurred. Therefore, unless the user confirms the error and ejects the disc with the error,
It does not proceed to the next processing.

Before the copy process, if a hardware abnormality (including mechanical failure or electrical failure) of the device such as a semiconductor laser failure occurs in the master or copy destination disk drive unit, the disk drive unit Does not enter the ready state, the copy processing is not started, and the copy processing instruction is not erroneously given to the failed disk drive unit. Therefore, it is possible to prevent useless execution of copy processing when a failure occurs in the device. Further, when a hardware abnormality of the disk drive unit occurs during the copy processing, the CPU 5 stops the copy processing, displays an error, and ejects each disk.

When the same master disk is further copied, the copied disk ejected from the disk drive unit is taken out and a new copy destination disk is used as the copy destination disk drive units 1b, 1b.
After being inserted into c, the same master disk is again inserted into the master disk drive unit 1a to perform copying. When copying another master disk, a new copy destination disk is inserted into the copy destination disk drive units 1b and 1c, and then another different master disk is inserted into the master disk drive unit 1a and copied. I do.

According to the configuration of the present embodiment, it is recognized that the copy destination disk and the master disk are inserted, the initialization processing is performed in the copy destination and master disk drive units, and the ready state for recording and reproduction is achieved. By starting the copy process after that, there is no waiting time during the copy start operation, and the copy process can be efficiently started.

In the initialization processing, the control tracks of the copy destination disk and the master disk are reproduced to detect the information of each disk, the capacities of both disks are compared and confirmed, and then the copy processing is started. A user can select and use a double-density disc or a triple-density disc with different recording capacities in the same device, and in this case, copy medium information such as the capacity size of the copy destination disc and the master disc. Since the check can be performed before the start, it is possible to perform an appropriate copy process according to the medium. As a result, it is possible to prevent erroneous copy processing when there is a problem with the recording capacity of the medium, and to avoid wasteful copy work.

Also, when a failure occurs in the disk drive unit, the operation related to the copy process is stopped, each disk is quickly ejected, and the copy process is not started. In this case, it is possible to prevent accidental copy processing.

As described above, it is possible to efficiently and properly perform the copy processing.
