Accordingly, the recording signal of the optical disc 21 read out by the optical pickup 22 is processed by the digital reproduction signal processing unit 24a for reproduction signal, and then transmitted to an external device and output as sound. The audio playback operation (S11) is performed, wherein the user can arbitrarily designate a highlight or climax section of the audio song being played according to his / her preference while listening to a sound sound output from an external device. do.

That is, when the climax setting key is selected by the user while playing an audio song, the microcomputer 26 starts the climax of the currently playing audio song C_S to create the audio index menu. : Climax Start) It is determined that the location is selected, and the corresponding recording location information is stored, or audio data to be played later is temporarily stored. First, the climax start location information selected by the user is stored. In the following description,

First, after storing the climax start position information C_S, the user determines whether the climax setting key is re-selected by the user, and when it is re-entered, the climax end of the audio song (C_E: Climax End) It is determined that the position is selectively selected (S12), and the previously stored climax start position (C_S) information and the previously stored climax end position (C_E) information are stored and stored as climax position information of the corresponding audio song (S13). Done.

Then, the climax position information of the plurality of audio songs recorded on the optical disc 21 is repeated by repeating the operations S11 to S14 until the index menu creation mode is released (S14), as shown in FIG. A lead-in area of the optical disc 21, that is, a lead in which management information for managing unit tracks, which are recording units corresponding to one audio song, is recorded. Recording is performed in the phosphorus area (S15).

Meanwhile, as illustrated in FIG. 5, the audio index menu additionally records a user's preference, i.e., a 1-bit identification flag that identifies the most recently selected audio song, so that the audio index can be subsequently recorded from the user. When a menu play operation is requested, priority playback is determined based on an audio song whose identification value of the flag is set to '1', and corresponding to an audio song whose identification value of the flag is set to '1'. Play the audio index menu from the user by additionally recording a 1-byte music selection count that allows the user to browse and play the climax first, or identify the most-selected audio song in the audio index menu. Is requested, priority playback based on the audio song having the highest count value (Count) Determined, so that the climax section of the audio track the music selection number (Count) is having the largest value can first search and a search result.

Meanwhile, as described above, when a climax setting key is selected and input by a user while playing an arbitrary audio song, the climax start position (C_S) of the currently playing audio song for creating the audio index menu. If it is determined to select and specify, and then temporarily store the audio data to be reproduced will be described. First, while temporarily storing audio data played after the climax start position, confirming whether the climax setting key is re-entered by the user, and re-entering, the climax end (C_E) position of the audio song. (S12), and temporarily stops the temporary storing operation of the reproduced audio data, and reads and reproduces the temporarily stored audio data, i.e., from the climax start position C_S to the end position C_E. The audio data is set and stored as climax audio data (Climax Audio) of the corresponding audio song (S13).

Thereafter, the above-described operations S11 to S14 are repeated until the index menu creation mode is released (S14), and the climax audio data for the plurality of audio songs recorded on the optical disc 21 is shown in FIG. Management information for managing unit tracks, which are recorded in the audio index menu configured as described above, that is a lead-in area of the optical disc 21, that is, a recording unit corresponding to one audio song as described above.
