Abstract: PURPOSE: An apparatus and a method for recording and playing an audio index menu of a disk recorder is provided to output index information by audio. CONSTITUTION: A specific interval is selected for each of audio music pieces recorded in a disk recorder based on a user's priority. An index menu is recorded, wherein the selected specific intervals are logically connected. Audio data or record position information corresponding to highlight or climax intervals of the audio music pieces are recorded. The priority is determined. The audio music pieces are reproduced based on the priority. Although an external set connected to an optical disk device is a digital audio set having no vidual display function, the index information with respect to the plurality of audio music pieces recorded in the disk recorder can be converted into audio sounds. The present invention has an advantage of alleviating conventional inconvenience that partial intervals should be reproduced by confirming a title cover displayed on an external appearance of the optical disk or sequentially checking the audio music pieces through a search function provided to the optical disk.
