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.
