DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an optical disk device.

[0002]

2. Description of the Related Art A radio broadcasting station broadcasts the theme music of a radio program called a jingle for a few seconds when a radio program starts broadcasting, ends broadcasting, or shifts to a commercial during a radio program. Alternatively, various sound effects are broadcast during a radio program. In recent years, in addition to such jingles and sound effects, program materials such as songs and interviews are often recorded on optical discs.

In order to broadcast a program with jingles and sound effects, an optical disc on which program materials such as songs and interviews used only in one broadcast of a radio program are recorded and a radio program broadcast are transmitted. There is a need for an optical disc on which the jingles used during the continuation are recorded.

In order to reproduce a program material, a jingle, and a sound effect using an optical disk device for reproducing one optical disk, an optical disk on which the program material is recorded and an optical disk on which the jingle and the sound effect are recorded are transferred to the optical disk device. It had to be worn alternately, cueed and played.

[0005] In this case, there is a possibility that an erroneous operation of mounting the optical disk by mistake when mounting the optical disk, or a delay that takes a long time to locate the track to be reproduced when mounting the optical disk, may be induced. . There is a demand to avoid such erroneous operations and delays.

[0006] In addition, erroneous operations and delays can be avoided by using a reproducing apparatus for reproducing an optical disk on which program material is recorded and two optical disk apparatuses for reproducing an optical disk on which jingles and sound effects are recorded.

However, in recent years, in addition to large-scale radio broadcasting stations nationwide, the number of small-scale radio broadcasting stations in close contact with local communities has increased. There is a demand for small-scale radio broadcasting stations to broadcast radio programs using a small number of broadcasting equipment.

[0008] In a small radio broadcasting station, there is a space limitation in the studio, and it is desired to avoid an increase in the number of reproducing devices. Also, when playing back more than two optical disks, it is necessary to change the optical disks during the broadcast as described above.
There is a risk of causing erroneous operation or delay. Avoid increasing the number of optical disk devices in proportion to the number of optical disks,
There is a request to reproduce data recorded on a plurality of optical disks by one optical disk device.

It is also conceivable to use a recording device for recording necessary data from an optical disk on which program material is recorded and an optical disk on which jingles and sound effects are recorded on one optical disk. By using this optical disk, reproduction can be performed by one optical disk device.

However, as described above, there is a demand for small-scale radio broadcasting stations to broadcast a radio program using a small number of broadcast equipment, and it is desired to avoid installing such a recording device in a studio.

[0011] Under such circumstances, there is a need for a reproducing apparatus capable of reproducing data from a plurality of optical discs with a single optical disc device without avoiding combining a plurality of optical discs into one optical disc. I have.

Further, in order to simplify operations during broadcasting, a function capable of reproducing a program is required. However, conventionally, one optical disk device program-reproduces one optical disk, and an optical disk changer device program-reproduces a plurality of optical disks.

[0013] However, the optical disk device is a program reproduction for programming the reproduction order of a plurality of tracks recorded on one optical disk. Since a broadcasting station uses a plurality of optical discs, program reproduction of a plurality of tracks on one optical disc cannot be used.

Also, in the optical disc changer apparatus, when a plurality of optical discs are programmed to be reproduced, it takes time to exchange the optical discs, or a malfunction may cause a broadcast trouble, which should be avoided. There is a need for a reproducing apparatus that can record a plurality of optical disks and external audio signals by one optical disk device and perform program reproduction.

[0015] Further, there is a case where a DJ (disc jockey) wants to perform an operation for adding a sound effect during broadcasting. However, during program playback, it is sometimes difficult to provide a desired jingle sound effect because it is set so that only program playback is performed. There is a need for a reproducing apparatus that can reproduce desired jingles and sound effects even during program reproduction.

[0016]

The control unit 13 controls the shock proof memory system controller 4 to store the digital compressed audio data in the RAM 5, and transmits the EFM data output from the EFM encoder 6 to the recording guide of the mini disc 7. The servo control circuit 12 is instructed to control the recording position in the groove.

When the stop instruction (STOP key) of the operation instruction unit 19 instructs to stop recording, the control unit 13 completes the recording process of the EFM data input up to that point, and then, The recording system is controlled so as to record management data such as track name and time information in the management data area of. The signal processing of the recording system is performed in this manner.

Next, the control of the reproducing system will be described. The reproduction of the EFM data from the mini disc 7 is performed by a laser light source,
An optical pickup 10 having a photodiode or the like irradiates a laser beam emitted from a laser light source to a mini-disc 7, and a return signal reflected from the mini-disc 7 is detected by a photodiode (not shown) to generate a detection signal which is an electric signal. This is done by outputting.

For reproduction, the recording guide groove of the mini disc 7 is
The laser beam emitted by the optical pickup 10 follows, and the optical pickup 10 receives the reflected light.
A photodiode (not shown) in the optical pickup 10 outputs a detection signal read by the laser beam irradiated to the recording guide groove to a reproduction amplifier (not shown).

The reproducing amplifier separates a focus error signal and a tracking error signal from the detection signal and outputs the signal to the servo control circuit 12. Further, the reproduction amplifier outputs the separated detection signal to the address decoder 14.
The address decoder 14 outputs EFM data to the EFM decoder 15 after demodulating the address data from the detection signal.

The focus servo control circuit and the tracking servo control circuit of the servo control circuit 12 control the focus actuator and the tracking actuator of the optical pickup 10 so as to guide the laser beam to the recording guide groove of the mini disk 7, and a lens (not shown) Drive.

The motor servo control circuit of the servo control circuit 12 controls the rotation of the motor 11 so as to rotate the mini disk 7 at a predetermined rotation speed. The slide servo control circuit controls a slide motor (not shown) to reproduce a target track from the tracks of the mini disc 7 and moves the optical pickup 10. The control of the reproduction system is performed in this manner.

Next, the signal processing of the reproduction system will be described. When a reproduction instruction for a certain track of the mini disk 7 is input from the reproduction instruction section (PLAY key) of the operation instruction section 19, the control section 13 reads the management data in the management data area of the mini disk 7 and based on the management data. The position of the optical pickup 10 is controlled by the servo control circuit 12 so that desired information data is read out, and reproduction is performed.

The EFM data output from the reproduction amplifier (not shown) of the optical pickup 10 via the address decoder 14 is supplied to the EFM decoder 15. The EFM decoder 15 decodes the EFM data to generate digital compressed audio data, and supplies the digital compressed data to the RAM 5 through the shock-proof memory system controller 4.

Is output via. The signal processing of the reproduction system is performed in this manner.

As described above, in addition to the recording / reproducing function of the mini-disc, the mini-disc recording / reproducing apparatus of this embodiment has a sampler. Hereinafter, the sampler will be described. A sampler storage unit 21 is connected to the shock-proof memory system controller 4. The sampler storage unit 21 stores digital compressed audio data output from the shock proof memory system controller 4.

A sampler operation instruction unit 22 is connected to the control unit 13. FIG. 3 is a specific button layout of the sampler operation instruction unit. As shown in FIG. 3, in the present embodiment, ten sampler N recording buttons for recording ten samples and one for reproducing the recorded samples are provided.
And zero sampler N playback buttons.

FIG. 4 is a layout diagram of data stored in the memory area of the sampler storage unit 21. Areas from sampler 1 to sampler 10 are allocated in the sampler storage unit 21 in advance. For example, in the sampler storage unit 21 having a storable data capacity of 30 minutes, the sampler stores 10 samples each having a storage time of 3 minutes.

The recording and reproduction of the sampler will be described. Regardless of whether or not it is recorded on the mini disc 7,
When an audio signal is input from the outside of the mini-disc recording device, the audio signal is converted into digital compressed audio data by the ATRAC encoder 3 and is shock-proof memory system controller 4
Is input to The shock proof memory system controller 4 sequentially outputs digital compressed audio data to the sampler storage unit 21.

When the operator presses, for example, the sampler 1 recording button, the storage of digital compressed audio data starts from the top of the sampler 1 memory area. The sampler storage unit 21 sequentially stores digital compressed audio data.

The remaining time that can be stored in the sampler 1 is displayed on the display unit 20 so that the operator can recognize the storable time. If the operator presses the sampler 1 recording button again, or if it exceeds 3 minutes, which is the maximum storable time of the sampler 1, the storage is stopped. In this way, digital compressed audio data obtained by sampling the audio signal input from the outside is stored.

Further, an arbitrary track may be reproduced from the mini disc and sampled. The operator operates the operation instruction unit 19
A track reverse search instructing section (TR-key) for performing a track reverse search, a track forward search instructing section (TR + key) for performing a track forward search,
A desired track is headed by a manual reverse search instruction unit (RVS key) for performing a manual reverse search and a manual forward search instruction unit (FWD key) for performing a manual forward search, and the track is temporarily stopped.

When the operator presses the recording button for sampler 1 after the heading is completed, the reproduction of the track is started and the storage in the sampler 1 is started. The EFM data of the track to be reproduced is converted into digital compressed audio data by the EFM decoder 15 and input to the shock-proof memory system controller 4.

The shock proof memory system controller 4 outputs digital compressed audio data to the sampler storage unit 21. Sampler storage unit 21
Stores digital compressed audio data sequentially.

Hereinafter, the remaining time that can be stored is displayed on the display unit 20 in the same manner as when inputting from the outside. If the operator presses the record button for sampler 1 again, or if it exceeds the maximum storable time of sampler 1 of 3 minutes,
Stop remembering. In this manner, digital compressed audio data reproduced from the mini disk is stored as a sample.

Next, reproduction will be described. Sampler 1 to play the sample stored in Sampler 1
When the playback button is pressed, the digital compressed audio data of the sampler 1 stored in the sampler storage unit 21 is played. The digital compressed audio data is output to the ATRAC7 decoder 16 via the shockproof memory system controller 4. After that, it is converted into an audio signal and output as in the case of reproducing the mini disc.

The mini disc recording / reproducing apparatus of the present embodiment
It can be used as a normal mini-disc recording / reproducing device, and can be used as a sampler for sampling an externally input audio signal and digital compressed audio data reproduced from the mini-disc.

Next, a description will be given of program reproduction using recorded data of a mini-disc and a sampler. In the mini-disc recording / reproducing apparatus, when only the mini-disc is normally reproduced, the tracks are sequentially reproduced such that the track numbers are sequentially increased from the track 1. Tracks 1 to 4 are recorded on the mini disc 7 of this embodiment. In this case, as shown in FIG. 5, the tracks are reproduced in the order of track 1, track 2, track 3, and track 4 on the mini disc.

In order to enable program reproduction of such a mini-disc and sampler, management data for program reproduction is created and managed collectively. In this embodiment, track 1, track 2, track 3, and track 4
And a sampler in which samples are stored in the sampler 1 and the sampler 2.

The operator presses the program reproduction management data creation instructing unit 23 connected to the control unit 13 in order to reproduce the mini disc and the sampler all at once. Control unit 13
Reads the management data recorded in the management data area of the mini-disc 7 and the sampler management data stored in the sampler storage unit 21 to create management data for program reproduction by combining the two management data. Then, it is stored in the program reproduction management data storage unit 24.

FIG. 6 is a structural diagram of the program reproduction management data stored in the program reproduction management data storage unit 24. In FIG. 6, as the program reproduction management data, the sampler stored in the sampler storage unit 21 follows the track recorded on the mini disc 7 and becomes the management data for program reproduction.

The medium selection data of the program reproduction management data is data for selecting whether to reproduce from the mini disk 7 or from the sampler storage unit 21. If the medium selection data is 1, the mini disc 7 is selected. If the medium selection data is 2, the sampler memory storage unit 21 is selected. When the medium selection data is 0
At this time, it is determined that the program reproduction order is not specified.

The number data of the program reproduction management data is the track number which is the management data of the mini-disc when reproducing from the mini-disc 7, and the sampler management data when reproducing from the sampler storage unit 21. , Respectively. If the number data is 1, it corresponds to track 1 or sampler 1. When the number data is 0, it is determined that the track number or the sampler number is not specified.

In the area of the reproduction order number 1, the medium selection data 1
And number data 1 are stored. At this time, track 1 of the mini disc is selected and reproduced. Similarly, track 2 of the mini disc 7, track 3 of the mini disc 7,
The management data is such that the track 4, the sampler 1, and the sampler 2 of the mini disc 7 are program-reproduced.

Reproduction is performed based on the program reproduction management data. When the play / pause instruction section (PLAY / PAUSE key) of the operation instruction section 19 is pressed,
Reproduction is performed based on the program reproduction management data stored in the program reproduction management data storage unit 24.

Since the mini disc and the sampler are collectively reproduced as a program, various operation instructions for performing the program reproduction are transmitted to the operation instruction section 1 of the mini disc.
The control unit 13 controls so as to use No. 9. The operator
As for the program reproduction, the operation instructing section 19 and the sampler operation instructing section 22 are not properly used, so that an easy operation can be performed.

FIG. 7 is a block diagram showing a first example of a track reproduction order when reproducing a mini-disc and a sampler based on the program reproduction management data. If the reproduction is based on the program reproduction management data, the track 1, the track 2, the track 3, and the track 4 are reproduced from the mini disk 7 as shown in FIG. 7, and then the sampler 1, the sampler 2 are stored from the sampler storage unit 21. To play each.

Further, complicated program reproduction can be performed. The control section 13 is connected to a program playback order instructing section 25 for specifying the playback order by the operator. The operator changes the order of program playback using the program playback order instructing unit 25.

FIG. 8 is a block diagram showing a second example of a track reproduction order when reproducing a mini-disc and a sampler based on the program reproduction management data. In the case of the program reproduction according to the second example, as shown in FIG. 8, the track 1 of the mini disc 7, the sampler 1 of the storage section 21 for the sampler, the track 2 of the mini disc 7, the track 3 of the mini disc 7, the storage section for the sampler The 21 sampler 2 and the track 4 of the mini disc 7 are reproduced. Such reproduction is also possible by rewriting the program management data.

At this time, after the reproduction of the track of the mini-disc 7 or the sampler in the sampler storage unit 21 is completed,
The playback is always paused automatically.
This is because when using the disc recording / reproducing apparatus of this embodiment in a broadcasting station or the like, an announcement or talk by a DJ is often inserted between music pieces, so that a certain track or sampler is followed by another track or sampler. This is because the sampler is rarely continuously reproduced.

During the DJ announcement or talk, the reproduction is temporarily stopped and the reproduction is paused at the track of the mini disk 7 to be reproduced next or at the head of the sampler in the sampler storage unit 21. When the DJ announcement or talk is finished and the next scheduled playback is performed, pressing the playback / pause instruction unit (PLAY / PAUSE key) of the operation instruction unit 19 starts playback from the beginning of the track or sampler. Is done. For this reason, it is possible to reduce the trouble of operation during broadcasting.

There are times when it is desired to insert a sound effect or the like into a program even during program reproduction. When the program is being played and the optical disk is paused, it is assumed that the DJ performs an announcement or a talk, and when a desired sampler N play button of the sampler operation instruction section 22 is pressed, the sampler storage section is opened. The digitally compressed data of the sampler N is output from 21 to reproduce jingles and sound effects.

From the above-described use of the mini-disc recording / reproducing apparatus of this embodiment, program materials such as music and interviews are recorded on the mini-disc 7, and jingles and sound effects are stored on the sampler of the sampler storage unit 21. It is desirable to memorize.

When a DJ makes an announcement or talks from the end of reproduction of a certain song or interview from the minidisk 7 until the next song or interview is played, the DJ uses the jingles and sound effects stored in the sampler at desired times. And broadcast content can be changed.

The recording / reproducing section 100 uses the mini disc 7
When the playback of the sampler is being performed,
When the play button for sampler N of No. 2 is pressed, the control unit 13
Does not reproduce the sampler ignoring the instruction, but outputs only the music and dialogue reproduced from the mini-disc 7. EF to shockproof memory controller 4
This prevents digital compressed audio data from being input from both the M decoder 15 and the sampler storage unit 21, thereby preventing malfunction.

Using the mini disc recording / reproducing apparatus of this embodiment, a mini disc on which jingles and sound effects are recorded is mounted on the mini disc recording / reproducing apparatus, and the jingles and sound effects are stored in a sampler. Also, audio data input from the outside is stored in the sampler. Only the mini-disc on which the program material is recorded is recorded / reproduced 1
00 can be always attached.

For this reason, necessary program materials, jingles,
Even if sound effects are recorded on multiple mini-discs, they can be reproduced using a single mini-disc recording / reproducing device. Can be avoided.

Further, even if there is a space limitation in the studio due to a small radio broadcasting station, the space required can be reduced because it is a single mini disk recording / reproducing apparatus.

Further, since the mini-disc and the sampler can be continuously reproduced by using the program reproduction in the ordinary mini-disc recording / reproducing apparatus, the operator can specify the reproduction order in advance, and there is a danger of erroneous operation during broadcasting. Can be avoided.

Further, it is possible to avoid time-consuming exchange of optical disks as in the case of reproducing a plurality of optical disks by a program as in the case of an optical disk changer device, and a trouble of a broadcast when a malfunction occurs. A plurality of tracks recorded on a plurality of minidiscs can be programmed by a single minidisc recording and reproducing apparatus.

Further, even when a program is being reproduced, when reproduction of the mini-disc is paused, reproduction can be performed from the sampler.
Can add jingles and sound effects stored in the sampler when desired.
