Abstract

A method and apparatus for recording and/or reproducing an audio highlight portion of an audio selection, and a recording medium for storing additional information therefor. A particular portion is designated on an audio track as a representative portion of the audio track. Reproduction related information for reproducing the representative portion is recorded to a predetermined area on the recording medium. Accordingly, a user can easily identify the contents of the track, such as for example, music, within a short time even if many different audio selections are recorded to individual audio tracks on a recording medium.
