PROBLEM TO BE SOLVED: To reduce an address error rate in a magnetic disk medium.SOLUTION: A resist is applied to a substrate prior to exposure and development to form a resist pattern. The substrate is etched using the resist pattern as a mask. When a master for forming a concave-convex pattern carrier having on a surface thereof a concave-convex pattern corresponding to a magnetic disk pattern is manufactured, if the burst mode in a servo pattern is a phase mode, a burst pattern in the servo pattern is provided by exposure at a position displaced radially inward from a reference position defined in relation to an address pattern in the servo pattern, by an amount xwhich satisfies |α|>6 and (0.009×α-0.065)×L<x<(0.009×α+0.065)xL, wherein αis a skew angle of a track T, and Lis a length in the radial direction of the track T. |
