The magnetic recording medium includes: a recording layer formed over a substrate in a predetermined concavo-convex pattern, convex portions of the concavo-convex pattern constituting recording elements; a filler underlayer film formed on the bottoms of concave portions of the concavo-convex pattern; and a DLC filler formed on the filler underlayer film in contact with the filler underlayer film so as to fill the concave portions. The filler underlayer film is made of a material selected from the group consisting of a Si-containing material, a Ge-containing material, and a carbide material containing one or more metal elements selected from Ti, Ta, Nb, Mo, Zr, Cr, W, V, and Hf.
