发明名称 Magnetic recording medium, recording/reproducing apparatus, and stamper
摘要 In a magnetic recording medium including a servo pattern region having a servo pattern formed of a concave/convex pattern having convex portions and concave portions and a data recording region, the region having a data track pattern, the concave portions are formed in an address pattern region of the servo pattern region such that the maximum lengths, which are located in the respective same radius regions of the respective lengths along the rotating direction of a substrate of the projecting end surfaces of the convex portions constituting the concave/convex pattern are set to first lengths that are double the minimum lengths along the rotating direction of the projecting end surfaces of the convex portions in the respective same radius regions. With this arrangement, the magnetic recording medium can securely read a magnetic signal and has a servo pattern having excellent surface smoothness.
