Claim Text:
1. A method for producing a magnetic recording medium, the method comprising: 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; forming a laminate layer on sidewalls of the concave portions of the magnetic material layer, the laminate layer including an organic material layer and an oxide layer and/or hydroxide layer deposited after the organic material layer thereby sandwiching the organic material layer between the magnetic material layer and the oxide layer and/or hydroxide layer; wherein the organic material layer exhibits a corrosion-inhibiting characteristic with respect to cobalt or cobalt alloy; and depositing a nonmagnetic material within the concave portions to form nonmagnetic regions.
