摘要： An optical disk includes at least one region along a radial direction, and a plurality of tracks provided in the at least one region. The at least one region contains address regions radially positioned on the plurality of tracks. In the address regions, data which is common between two adjacent tracks of the plurality of tracks is recorded at positions aligned along the same radial direction on the two adjacent tracks, and data which is not common between the two adjacent tracks is recorded at positions along different radial directions on the two adjacent tracks.

摘要： A disklike storage medium on which information is recorded at higher density by reducing the redundancy of the address part and a tracking method using the medium are disclosed. The disklike storage medium where a track is divided into areas and address data is recorded in the areas is so adapted that an error detecting code for identifying the data common to adjacent tracks out of the address data is added to the common data. Thus, a data synchronization processing performed when the address data is reproduced is realized without any special synchronization pattern.

摘要： While a control portion changes the laser power stepwise with a laser power control portion, the optical disk apparatus of the present invention compares a predetermined level with an output by a detector that detects the correlation between a pattern to be recorded on the optical disk and the reproduction signal of the recording pattern detects as the minimum recording power the recording power when the originally smaller of the predetermined level and that output by the detector becomes larger than the other, and sets the optimum recording power to a power obtained by multiplying the detected minimum recording power by a certain factor.
