<First Embodiment>
In this embodiment, an information recording / reproducing apparatus that records identification information corresponding to main information recorded first among a plurality of main information recorded on a recording medium in a program information area and generates one program will be described. .

  FIG. 1 is a schematic block diagram showing the overall configuration of the recording / reproducing apparatus.

  In the figure, a magneto-optical disk 1 on which music information and the like are recorded, a spindle motor 14 that rotationally drives the magneto-optical disk 1, and an optical pickup 4 that irradiates the magneto-optical disk 1 with laser light during recording / reproduction. And.

  At the time of recording, the optical pickup 4 irradiates the magneto-optical disk 1 with a high level laser beam for heating the recording track to the Curie temperature, and at the time of reproduction, a low level laser for detecting data from the reflected light. Light is applied to the magneto-optical disk 1.

  A magnetic head 2 that applies a magnetic field modulated by data to be recorded during recording to the magneto-optical disk 1 is disposed at a position facing the optical pickup 4 with the magneto-optical disk 1 interposed therebetween.

  The optical pickup 4 and the magnetic head 2 can be moved in the radial direction of the disk 1 by a feed motor 15.

  During reproduction, information read from the optical pickup 4 is sent to the RF amplifier 5. The RF amplifier 5 processes this information and extracts a reproduction RF signal, a tracking error signal, a focus error signal, groove information which is an absolute position signal recorded on the magneto-optical disk 1, and the like.

  The extracted RF signal is sent to the encoder / decoder circuit 6, the tracking error signal and the focus error signal are sent to the servo circuit 17, and the groove information is sent to the address decoder 22.

  The servo circuit 17 generates various servo drive signals according to a tracking error signal, a focus error signal, and an instruction from a recording / reproduction control unit (hereinafter referred to as “system control microcomputer”) 18, and controls the driver circuit 16 to control the spindle motor. 14, the feed motor 15 and the optical pickup 4 are driven.

  The extracted reproduction RF signal is subjected to signal processing such as demodulation and error correction by the encoder / decoder circuit 6 and then sent to the memory controller 7. The memory controller 7 writes the demodulated data into the memory 8.

  The data on the disk 1 may be compressed by various compression formats, and the data reading speed from the disk 1 and the audio reproduction speed are different. Therefore, the memory controller 7 adjusts the reading speed to adjust the memory 8. The data is read out from the data and sent to the audio compression / decompression circuit 9.

  The voice compression / decompression circuit 9 decompresses the data by decompressing the data according to a predetermined format and sends the data to the D / A converter 11. The D / A converter 11 D / A converts the transmitted signal. The D / A converted signal is sent to the audio output terminal 13 and output as an analog signal.

  The address information output from the address decoder 22 is sent to the system control microcomputer 18 via the encoder / decoder circuit 6 and used for various control operations.

  The audio compression / decompression circuit 9 compresses the audio data by a predetermined compression method and sends it to the memory controller 7, and the memory controller 7 writes the sent data in the memory 8. At the same time, the digital interface circuit 21 extracts the music number information from the digital input signal and sends it to the system control microcomputer 18.

  The memory controller 7 reads the data stored in the memory 8 in accordance with the data write timing to the disk 1 and sends it to the encoder / decoder circuit 6. The encoder / decoder circuit 6 performs modulation, addition of an error correction code, etc., and sends it to the head drive circuit 3.

  The head drive circuit 3 drives the magnetic head 2 and applies a magnetic field to the magneto-optical disk 1. At the same time, a high level laser beam for heating the recording track output from the optical pickup 4 to the Curie temperature is irradiated on a portion of the magneto-optical disk 1 where a magnetic field is applied by the magnetic head 2. Data is recorded on the magneto-optical disk 1.

  Management information recorded on the mini-disc is used to record / reproduce the mini-disc. The management information includes an address on the disc 1 where the audio data is recorded, the number of songs recorded on the disc 1, the title of the song, and the like, and the user can arbitrarily record / edit the data on the disc. In the recordable disc, each time recording / editing by the user is performed, management information is rewritten accordingly, and song switching information (song number information) detected when recording audio data is also stored in this management information area. To be recorded.

  In Hi-MD which is a new MD standard, a part of this management information is provided with a program information area where a user can register the order of reproducing songs in an arbitrary order, and the program contents are recorded in the program information area. Thus, when the disc is inserted into the Hi-MD program function compatible device, the device can read the program content and play the music in the order in accordance with the program.
