Abstract:
1. A method of manufacturing a magnetic recording medium, the method comprising: forming a magnetic layer on a non-magnetic substrate; forming a mask layer on the magnetic layer; forming a resist layer which is patterned into a predetermined shape on the mask layer; patterning the mask layer into a shape corresponding to the resist layer using the resist layer; patterning the magnetic layer into a shape corresponding to the mask layer using the patterned mask layer; and removing the mask layer that remains on the magnetic layer by reactive plasma etching, wherein the reactive plasma etching is performed in an atmosphere containing an organic compound having at least one kind or plural kinds of functional groups selected from the group consisting of a hydroxyl group, a carbonyl group, a hydroxy carbonyl group, an alkoxy group, and an ether group.
