ABSTRACT:
An audio disk has a first audio zone and a second audio zone. In the first audio zone, both of a plurality of tracks each including a single piece of music and a first management information including first control information for allowing each track to be reproduced are recorded. The music is composed of audio data produced from either a linear PCM signal or a signal produced by applying lossless compression to the linear PCM signal. In the second audio zone, music composed of audio signal produced under lossy compression, a plurality of files each storing a signal of a single piece of music subjected to the lossy compression, and second management information including second control information for allowing each file to be reproduced are recorded. Each piece of music stored in each file corresponds to the music included in any one of the tracks in the first audio zone.
