ABSTRACT:
On an optical disk, information is recorded on both grooves and lands as guide tracks for guiding a light beam. The width of each groove and that of each land are set substantially equal to each other. A plurality of series of pits representing address information are formed in the grooves so that the series of pits in a groove and the series of pits in the adjacent grooves are located in different radial directions of the optical disk. Address pits are not formed in any of the tracks formed by the lands. When the light beam scans the track on the land, the address information is obtained by crosstalk of the series of address pits formed in the track on the groove. This structure enables the management of the addresses of tracks having thereon no address pits. When obtaining the address information by reproducing the series of address pits on the groove, since no crosstalk occurs, accurate address information is obtained.
