Methods of production for corrosion-resistant bit patterned media (bpm) and discrete track media (dtm)

Abstract

A method for producing a magnetic recording medium in one embodiment includes forming a magnetic material layer above a substrate, transferring an uneven pattern to the magnetic material layer to form concave portions and convex portions, the convex portions being magnetic regions, depositing a nonmagnetic material above the concave portions to form nonmagnetic regions, forming an oxide layer and/or hydroxide layer above the magnetic regions of the recording layer, and forming an organic material layer which exhibits a corrosion-inhibiting characteristic with respect to cobalt or cobalt alloy above the oxide layer and/or hydroxide layer.
