Patent ID: 8828483

Claim:
A method of manufacturing a magnetic recording medium having a magnetically separated magnetic recording pattern, the method comprising: forming a magnetic layer on at least one surface of a non-magnetic substrate; forming a mask layer which covers the surface of the magnetic layer; forming a resist layer patterned to have a shape corresponding to the magnetic recording pattern on the mask layer; patterning the mask layer to have the shape corresponding to the magnetic recording pattern 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 the surface where the recess is formed; flattening the surface of the non-magnetic layer until the mask layer is exposed; removing the exposed mask layer to form a protruding portion of the non-magnetic layer protruding outwardly from an inner side of the recess relative to the surface of the magnetic layer; and then removing the protruding portion; forming a protective layer which covers the surface where the protruding portion is removed.
