ABSTRACT:
An optical disk includes: a plurality of recording tracks, each of the recording tracks having a data area for storing data, and a servo control information area for storing servo information; and tracking pits respectively formed on n neighboring recording tracks, which are adjacent to each other in a radial direction of the optical disk, where n is an integer not less than 3. The tracking pits are located in the servo control information area of each of the n neighboring recording tracks and are spaced apart from each other by a distance not less than a radius of a beam spot for reading data from the optical disk. The tracking pits of the n neighboring recording tracks are located on different radial lines of the optical disk.
