Disclosed is a method of manufacturing a magnetic recording medium having a clear magnetic recording pattern through a simple process. The method includes: forming a magnetic layer on the non-magnetic substrate; forming a mask layer which covers a surface of the magnetic layer; forming a resist layer on the mask layer; patterning the resist layer using a stamp; patterning the mask layer using the resist layer, forming a recess by partially removing a portion of the magnetic layer not covered by the mask layer; forming a non-magnetic layer which covers a surface where a recess is formed; flattening a surface of the non-magnetic layer until the mask layer is exposed; removing an exposed mask layer; removing a protruding portion of the non-magnetic layer; and forming a protective layer which covers a surface where the protruding portion was removed.
