摘要： A disk-shaped storage medium allowing the redundancy of an address part to be reduced and data to be recorded with a higher density, and a tracking method using the same are provided. In a disk-shaped storage medium in which a track is divided into a plurality of areas and address data are positioned in the plurality of areas, error detection codes are added to data common to adjacent tracks of the address data for identifying the data common to adjacent tracks. This enables the synchronous process to data in reproducing the address data to be carried out without using a unique synchronization pattern.

摘要： An optical disk can detect reliable address data without the need of checking the validity of synchronous detection of segment numbers. The optical disk has one or more tracks, and address data is arranged in a distributed manner on the tracks. A generating polynomial that generates an error detection code of a segment number included in the address data, which represents location information in the disk rotatory direction, is made different from a generating polynomial that generates an error detection code of a track number included in the address data, which represents location information in the disk radial direction.
