A magnetic recording medium has data track patterns formed by concave/convex patterns in data recording regions on at least one surface of a substrate and servo patterns formed by concave/convex patterns in servo pattern regions between the data recording regions. The concave/convex patterns include convexes, at least protruding end portions of which are formed of magnetic material, and concaves. A burst pattern region of each servo pattern region includes N (where N is at least two) burst regions, in which burst patterns, where plural burst signal unitary parts are aligned along a direction of rotation, are formed as the servo patterns. The burst signal unitary parts formed in M (where M is no greater than (N−1)) out of the N burst regions are concaves, and the burst signal unitary parts formed in L (where L is equal to (N−M)) out of the N burst regions are convexes.
