Disk record medium, and method and apparatus for recording and
reproducing information onto and from the same
摘要:
In recording and/or reproducing data into and from a disk record medium having a record medium in which a plurality of tracks are arranged radially, the record area is divided into a plurality of zones, and a clock frequency is assigned to each zone. The data recording and/or reproducing are performed according to the clock of the frequency assigned to the respective zone. Each zone is subdivided to include a plurality of tracks, and a clock having a different frequency is assigned to each zone. Each frequency is set in such a manner that the record capacity of the track gradually becomes larger as the zone is nearer to the outer zone.
