To provide a method for manufacturing a magnetic recording medium, with which a smoothing process of a magnetic layer which has a sharp magnetic recording pattern is conducted at a high speed.
The method for manufacturing the magnetic recording medium includes a step for forming a magnetic layer 2 on a nonmagnetic substrate 1; a step for forming a carbon mask layer 20 on the magnetic layer 2; a step for forming a resist release layer 21 on the carbon mask layer 20; a step for forming a resist layer 3, which is patterned by a shape corresponding to the magnetic recording pattern on the resist release layer 21; a step for partially removing the resist release layer 21, the carbon mask layer 20 and the magnetic layer 2 by using the resist layer 3 as a mask; a step for forming a nonmagnetic layer 4, which covers a surface from which the magnetic layer 2 has been removed, and which buries at least a part of the resist release layer 21; and a step for subjecting the nonmagnetic layer 4 to grind processing, until the magnetic layer 2 is exposed.
