PROBLEM TO BE SOLVED: To improve production efficiency by forming a recording layer with an uneven pattern. SOLUTION: The recording layer 22 is formed by an irregular servo uneven pattern in which at least a part of any one of a concave part and a convex part of a basic servo uneven pattern is divided in the radial direction Dr for the basic servo uneven pattern in which a part of the servo region, a grid region for recording either information of 0 or 1 is a concave part unit region CU constituting a concave part, and a grid region for recording the other one is a convex part unit region PU constituting a convex part.
