<P>PROBLEM TO BE SOLVED: To provide an optical disk playback device capable of accurately verifying an error of TOC information, and an optical disk playback method. <P>SOLUTION: A management data acquiring part 21 acquires management data recorded in the innermost circumference of an optical disk 1 and stores the management data in a management data storing part 30. If information that track classification is an audio track is associated with a head track of a data area in the management data, a data track extracting part 22 extracts a track with which the information that the track classification is a data track is associated in the management data. If information that track classification is the audio track in identification information in the data area is associated with the track extracted by the data track extracting part 22, a track classification verifying part 23 changes the management data stored in the management data storing part 30 so as to associate the information being an audio track with the track. <P>COPYRIGHT: (C)2012,JPO&INPIT |
