PROBLEM TO BE SOLVED: To alternately record the addresses of grooves and the addresses of lands adjacent to the grooves in the grooves, and to specify the addresses of the lands in accordance with the addresses of the grooves adjacent to both sides.SOLUTION: In the optical information recording medium adopting CAV(Constant Angular Velocity) or zone CAV, wobble grooves are preliminarily formed, and information is recorded in the grooves and lands adjacent to the grooves, and addresses are recorded with the wobble signals of the grooves, and a first section in which addresses N are recorded with the wobble signals and a second section in which addresses (N-1) or (N+1) are recorded with the wobble signals are alternately disposed, and the first section of one groove track between two groove tracks is made coincident with the second section of the other groove track, and the addresses of the grooves are read from the first section, and the addresses of the lands are read from the first and second sections positioned at both sides of land tracks, and respectively recorded with the same address. |
