Next, the operation will be described. When a power switch (not shown) is turned on, the system control circuit 17
Of the memory and initialization of the optical pickup 5 to the initial position are performed. Next, it is determined whether or not the disk 1 is mounted on the disk holder 2, and after the disk 1 is mounted, a focus search is instructed to the pickup servo circuit 6. As a result, the spot light emitted from the optical pickup 5 to the disk 1 converges to a predetermined diameter. When the focus search is completed, the pickup servo circuit 6 is instructed to start focus servo. The focus servo is for automatically adjusting the objective lens of the optical pickup 5 by moving the objective lens up and down following the surface deviation of the disk 1.

Next, a wait (pause) for a predetermined time is performed, and a command input from the key input unit 19 is waited. When a command is input from the key input unit 19, processing corresponding to the input command is performed. On the other hand, if there is no command input, the process ends. This command instructs a search operation, a play operation, or the like. When the command instructs a search operation, movement control processing of the optical pickup 5 is performed. In the movement control processing of the optical pickup 5, the target track storing the target data is confirmed by the contents of the memory in the system control circuit 17 storing the TOC according to the search command input from the key input unit 19, and based on this, Optical pickup 5
The number of tracks from the current position to the target track is calculated, and the target track is searched. On the other hand, when the command is a command for instructing a play operation, it is determined whether or not the data read from the disk 1 is ROM data.
If the music data or audio data is not OM data, the audio mute is turned off and the music data, audio data, and video signal read from the disk 1 are reproduced.

FIG. 2 is a flowchart for explaining the menu registration operation when displaying an image reproduced from the data read from the disk 1 on the CRT device 24. The operation at the time of menu registration will be described below with reference to FIG. First, when a menu selection instruction is input by the menu key 19a of the key input unit 19 (step S101), a screen 26 for menu selection shown in FIG.
Is displayed (step S102). Further, the monitor operation, the random operation, and the monitor operation displayed on the screen 26 shown in FIG.
A desired operation is selected from the intro scan operation or the like (step S103). This feature selection is performed by key operation of a corresponding number on a ten-key (not shown) of the key input unit 19. When, for example, an intro scan operation is selected by this feature selection, the screen is immediately switched to the screen 27 shown in FIG. 3 with the chapter number “0” (step S104).
