    Abstract: A method for producing a magnetic recording medium having a magnetically partitioned magnetic recording pattern on a surface of a nonmagnetic substrate, which comprises the following steps. Step (A) of forming a magnetic layer on a non-magnetic substrate, step (B) of forming a carbon layer on the magnetic layer, step (C) of forming a resist layer on the carbon layer, step (D) of forming a negative pattern of magnetic recording pattern on the resist layer, step (E) of removing the portions of resist layer and carbon layer in regions corresponding to the negative pattern, step (F) of removing at least a surface layer portion of the magnetic layer in the regions corresponding to the negative pattern, and optional step (G) of removing the residual resist layer and carbon layer. The produced magnetic recording medium has a recording/reproducing property equal to or better than conventional ones and exhibits a high recording density.
