摘要： On an optical disk medium according to the present invention, address information is recorded along a wobbling track groove 2. The track groove 2 is made up of a plurality of unit sections 22, 23. Each of these unit sections 22, 23 has side faces that are displaced periodically in a disk radial direction. This displacement oscillates at a single period in a tracking direction. However, the displacement pattern differs depending on “each bit of address information (subdivided information)” allocated to each of the unit sections 22, 23.

摘要： A method for writing a signal on an optical disk is disclosed. The optical disk comprises a track groove on a recording surface thereof, on which information is recorded along the track groove on a block-by-block basis each said block having a predetermined length and where an identification mark indicating the beginning of each said block, has been formed on the track groove. Writing is started before the identification mark, located at the beginning of at least one block on which the signal should be written, is reached and writing is ended after the identification mark located at the end of the at least one block on which the signal should be written has been passed.
