METHOD FOR MANUFACTURING MAGNETIC RECORDING MEDIUM, AND MAGNETIC RECORDING/REPRODUCING DEVICE

摘要

Provided is a method for manufacturing a magnetic recording medium having magnetically separated magnetic recording patterns. The method includes steps performed in the following order; (a) a step of forming a magnetic layer on a nonmagnetic substrate, (b) a step of exposing to reactive plasma or reactive ions a surface layer section of the magnetic layer in a region from which the magnetic layer is to be removed, and (c) a step of irradiating the magnetic layer with an inert gas. Preferably, (b) a step of removing the surface layer section of the magnetic layer in the region from which the magnetic layer is to be removed, (c) a step of exposing to reactive plasma or reactive ions the magnetic layer region from which the surface layer section is removed, and (d) a step of irradiating the magnetic layer with the inert gas are performed after the step (a). The obtained magnetic recording medium does not corrode due to oxidation or halogenation of the magnetic layer surface.
