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 convex portions are formed in an address pattern region of the servo pattern region such that the maximum opening lengths, which are located in the respective same radius regions of the respective opening lengths along the rotating direction of a substrate of the concave portions constituting the concave/convex pattern are set to first lengths that are double the minimum opening lengths along the rotating direction of the concave 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.
