摘要：
An optical disk has a recording region divided into zones, each zone including physical tracks which are divided into a number of sectors. The optical disk further includes a structure management table which stores an attribute for each zone indicating whether the corresponding zone is a recording area which permits rewriting of a recording area that does not permit rewriting.
