Patent ID: 8394514

Claim:
A method for producing a magnetic recording medium having a magnetically partitioned magnetic recording pattern on at least one surface of a nonmagnetic substrate, characterized by comprising the following steps (A) through (F) carried out in this order: (A) a step of forming a magnetic layer on a non-magnetic substrate, (B) a step of forming a carbon layer on the magnetic layer, (C) a step of forming a resist layer on the carbon layer, (D) a step of forming a negative pattern of the magnetic recording pattern on the resist layer, (E) a step of removing portions of the resist layer and portions of the carbon layer in regions corresponding to the negative pattern of the magnetic recording pattern, (F) a step of removing a surface layer portion of the magnetic layer in each region corresponding to the negative pattern of the magnetic recording pattern, and then, (F′) a step of exposing each region of the magnetic layer, which has been exposed by the removal of the surface layer portion of the magnetic layer in step (F), to a fluorine-containing gas ion and then an oxygen gas ion in this order.
