摘要：An optical disk physical has a recording region divided into zones, each zoneincluding physical tracks adjacent to each other. An integer number of sectors are

provided in each physical track. The angular recording density is higher in the moreoutward zones such that the linear recording density is substantially constantthroughout the recording region, and logical tracks are formed of a predeterminednumber of sectors, independent of the physical tracks. The conversion between thelogical track and sector addresses read from the disk and the linear logical addressessupplied from a host device is easy. The addresses written in headers of the sectors in thelogical track in which data are actually recorded, including substitute sectors used inplace of defect sectors, are preferably consecutive to further facilitate the conversionbetween the logical track and sector addresses read from the disk and the linear logicaladdresses supplied from the host device. Each of the zones can be set to serve as any ofthe different types of recording area, independently of other zones.
