ABSTRACT:
An optical disk according to the present invention has data recording tracks of lands and grooves. Each of the data recording tracks has a length corresponding to a revolution of the disk and includes a plurality of track sectors. The data recording tracks of lands and grooves are connected alternately to form a continuous data recording spiral. Each of the track sectors has a preformatted identification signal part for representing sector address data and has a data recording part for recording data. The identification signal part has a first address data region and a second address region. The first address data region and the second address data region are shifted by the same predetermined distance in opposite directions from the center of a groove track in the radial direction of the disk. The first address data region is set to represent the address of a groove track sector, and the second address data region is set to represent the address of a land track sector adjacent to the groove track sector.
