PROBLEM TO BE SOLVED: To record and reproduce a plurality of relevant data synchronously on one disk. SOLUTION: When a plurality of data recorded on a plurality of data recording areas 12, 15 having the different application of disks or different data formats mutually have relevance, discriminating data displaying relevant information are recorded on TOCs(tables-of-contents) 11, 14. Such discriminating data are recorded at the time of the manufacture of the disk at the case of the reproducing exclusive disk, and provided as the recorded disk. The data are recorded on the disk or a memory so that a time base can be lengthened at the time of the read of at least one data so as to synchronize mutual relevant data at the time of recording and at the time of reproduction or at the time of the recording of other data as well while reproducing one data. |
