摘要：
A disk recording apparatus being compatible with disks whose storage capacity is different, in which a first and a second recording mode can be set. In the first recording mode, linear track numbers are assigned, and in the second recording mode, offsetting track numbers are assigned, so that some of the tracks in both formats have the same track numbers to provide compatibility.
