发明名称 Corrosion-resistant bit patterned media (BPM) and discrete track media (DTM) and methods of production thereof
摘要 In one embodiment, a magnetic recording medium includes a magnetic recording layer including a magnetic material characterized by having convex and concave portions, the convex portions acting as magnetic regions, a nonmagnetic material positioned within each concave portion of the magnetic material which act as nonmagnetic regions that separate the magnetic regions, an organic material layer which exhibits a corrosion-inhibiting characteristic with respect to cobalt or cobalt alloy positioned on a nonmagnetic region side of each concave portion, and an oxide layer and/or hydroxide layer positioned adjacent the organic material layer on a magnetic region side of each concave portion of the magnetic material. In another embodiment, the magnetic recording medium may be a patterned recording layer having a protective film, and the oxide layer and/or hydroxide layer may be positioned at least in defect portions of the protective film.
