摘要： PROBLEM TO BE SOLVED: To prevent interference of a wobble signal from both side groups for the land track when a groove is wobbled to control the disk rotation and to generate a clock signal, in an optical disk of a land/groove recording system having a pre-format ID for each sector.
SOLUTION: In the optical disk of a zone format, in which a disk surface is divided into a plurality of zones by a radial position, in the optical disk of land/groove recording format in which the track of one rotation of the disk is constituted in sectors of the number of integer, wobble of the cycles of the prescribed integer is added to a groove in each sector. Wobble of each cycle is adjusted so as to be made the same phase between adjacent groups in each zone. Wobble of the cycles of the prescribed integer is divided into a plurality of unit wobble columns for each prescribed unit cycle, Binary information relating to a sector address is expressed by modulating a period of wobble in the unit wobble column. Prior to the binary information relating to the sector address, synchronous information expressed in the wobble is added.

摘要： PROBLEM TO BE SOLVED: To detect easily and surely a connecting point between a land track and a group track without lowering recording density by forming a binary differential signal from the differential signal of a photodetector, forming a discrimination signal gate signal from the differential signal, and detecting timing of a recording sector discrimination signal from the binary differential signal at the time of recording or reproduction of a disk medium. SOLUTION: When a light beam enters from an information recording part in a prescribed groove recording sector to the discrimination signal part of the next groove recording sector, a corresponding tracking error signal is outputted. Then, there is a discrimination signal part that is shifted by a half of the groove width in the inner periphery of a disk, a corresponding tracking error signal is outputted. By comparing the size of the two error signals, a servo can be controlled to the track center. Polarity information indicating whether the sector is the land sector or the group sector is contained in the discrimination signal other than the address of the sector, so that the polarity can be set by surely reading the discrimination information under normal tracking.
