FIG. 1 is a block diagram of an MD recording / reproducing apparatus which is an embodiment of a disk recording / reproducing apparatus according to the present invention. The MD recording / reproducing apparatus shown in FIG. 1 is used by being incorporated in the aforementioned MD / CD system. FIG.
In the figure, reference numeral 1 denotes an RF matrix amplifier, which processes an RF signal and a servo signal used for recording and reproduction of an MD. The RF matrix amplifier 1 includes a focus error signal and a tracking error signal necessary for controlling the focus and tracking of the optical pickup assembly 11, and an FM modulation signal of ADIP (ADress In Pregroove) which is address information of a recordable MD recording area. To the servo and EFM / ACIRC encoder / decoder 2. The RF matrix amplifier 1 also includes an APC circuit for keeping the amount of emitted laser light constant.

Reference numeral 2 denotes a servo, EFM / ACIRC encoder / decoder, and a servo controller and an EFM / ACIRC.
And a C encoder / decoder unit. The servo control unit receives a focus error signal and a tracking error signal from the optical pickup in the RF matrix amplifier 1 and receives a focus servo signal and a tracking servo signal of the optical pickup, and further, a disc motor control servo signal and an address from the ADIP signal. The information is taken out, the optical pickup and its feeding mechanism are controlled, and the rotation of the disk is controlled.

At the time of encoding, the EFM / ACIRC encoder / decoder unit uses an ATRAC (Adaptive TRansfo
ADC (Analog-Digital Converter) 1 encoded by rm Acoustic Coding encoder / decoder 3
ACIR of the audio input signal converted from A / D
An error correction code is added using C, EFM modulated, and output to the optical pickup assembly 11. At the time of decoding, the EFM signal input from the RF matrix amplifier 1 is EFM-demodulated, error-corrected by ACIRC, and
Output to ATRAC encoder / decoder 3. This signal is ATRAC decoded, and the DAC (Digital-Analog
Converter 9 converts the signal into a digital audio output signal.

Reference numeral 3 denotes an ATRAC encoder / decoder, which compresses and decompresses audio for MD recording and reproduction. here,
The voice compression data is compressed to about 1/5 of the original data, and the rotation speed of the MD is about 5 times or 1 times as large as the input and output amount of data because the rotation speed of the MD is the same as the specified speed of the EFM.
Therefore, a DRAM 4 called a shock-proof memory is used as a data buffer. Reference numeral 5 denotes a system controller composed of a microcomputer or the like, which issues an instruction to the RF matrix amplifier 1, the servo, and the EFM / ACIRC encoder / decoder 2 to perform normal reproduction, recording, pause, stop, search, and the like. Also, the servo and EFM / ACIRC encoder / decoder 2 output the TOC recorded on the MD.

Further, a disk name (for example, “MY BEST”) related to the present invention can be written and read into the memory 6 in advance. Reference numeral 7 denotes a key matrix, which receives an instruction from a user's key operation, and
Normal playback, recording, pause, stop,
Control of search and the like, reading and writing of the memory 6, a request for display on the display 8, and the like are performed. Also,
Similarly, the key matrix 7 receives an instruction by a user's key operation, and sends a “BEST HIT” function or “DISC NAME” related to the present invention to the system controller 5.
Requests for features are also made.

The MD recording / reproducing apparatus having the above-described structure is an MD / C
It is incorporated in the D system, and operates as follows by instructing the “Best Hit” function by operating a specific key of the key matrix 7. In this example,
It is assumed that the CD player has a CD changer.

When the "Best Hit" function is designated, one of a plurality of single CDs built in the CD changer is designated.
Only the songs are sequentially and sequentially recorded on the MD. Next, at the end of the recording, the disk name “MYBEST 1” written in the memory 6 in advance is read and recorded on the MD. Subsequently, another MD without a disc name
Is set in the MD recording / reproducing apparatus,
The disc name "MY BEST 2" in which "1" of "Y BEST 1" has been rewritten to the serial number "2" is called out and recorded on the MD. Similarly, in the case where an MD without a disc name is recorded by the "Best Hit" function, the disc name rewritten to the next number after the serial number from the memory 6 is automatically registered in the MD. When the above function is used by overwriting a previously recorded MD, it is convenient to use the recorded MD after erasing it once.

As described above, when the MD is recorded by the "Best Hit" function, the disc name is registered so that each MD can be automatically identified. When such an MD is reproduced, the registered disc name is registered. Can be displayed on the display 8. The disk name written in the memory 6 in advance can be changed.

Next, the above-mentioned disk name automatic registration operation will be described with reference to the flowchart shown in FIG. First,
In step S1, when the user instructs the "BESTHIT" function by operating the key of the key matrix 7, the system controller 5 executes the BEST based on the key input information.
Start recording using the T HIT function. Next, in step S2, the system controller 5 determines whether or not recording by this function has been completed.
Returning to step 2, if yes, proceed to step S3. Then
In step S3, it is checked whether a disc name has already been registered in the MD, and if yes, it is determined that the disc name is appropriate and the process ends. This is because there is a case where recording is not performed without recording all the recordable time of one MD by one operation.

If the answer to step S3 is NO, the process proceeds to step S4, where it is determined whether or not a disc name has been written in the memory 6 in advance. If NO, the process proceeds to step S10 to perform the normal "DISC NAME" function Desired disk name, for example, "MY BEST 1",
And write it to the MD. Next, the process proceeds to step S11, where it is determined whether or not the disk name is to be stored. If yes, the process proceeds to step S9. If the answer to step S4 is yes, the process proceeds to step S5, and a disk name previously written in the memory 6, for example, "MY BEST 1" is called.

Then, the process proceeds to a step S6, where the last number "1" of the disk name "MYBEST 1" called from the memory 6 is incremented and displayed. Next, the process proceeds to step S7, and it is determined whether or not to change the disk name previously written in the memory 6 (called in step S6). If the answer to step S7 is yes, the process proceeds to step S10, where the normal "DISCN"
A process based on the "AME" function is performed, and the disc name is changed to another desired disc name (written to the MD). Then, the process proceeds to step S11, and it is determined whether or not the disc name is stored in the memory. The process proceeds to step S7, where the result is stored in the memory 6, and if no, the process ends.
If the answer is no, the flow advances to step S8 to write the incremented disk name "MY BEST 2" to the MD. Next, the process proceeds to step S9, where the registered disk name "MY BEST2" is written into the memory 6, and the MD recording by the next "BEST HIT" function is awaited.

In the above embodiment, "BEST H
As an IT function, the case where only the first song of a plurality of single CDs built in a CD changer is automatically recorded sequentially and sequentially on an MD has been described, but single CDs are played one by one without using a CD changer. It is also possible to automatically record only the first song in the MD sequentially and automatically on the MD.

As described above, "BEST HIT"
Easy to use MD / CD that automatically registers the disc name to your original MD created by the function
The system can provide.
