Abstract:
A magnetic recording medium with a granular magnetic recording layer excellent in corrosion resistance is provided. In one embodiment, after formation of, on a non-magnetic substrate, an NiTa adhesion layer, a soft magnetic layer, a Ta intermediate layer, an Ru intermediate layer, and a Co alloy granular magnetic recording layer, hydrogen (H2) plasma processing is applied to the surface of the Co alloy granular magnetic recording layer. Then, a DLC protective film layer is formed and a lubricant layer is coated.
