摘要： To provide a magnetic recording medium manufacturing method capable of transferring a pattern that can serve as a source for forming anodized alumina-nanoholes with high precision and realizing high productivity, and a large-capacity magnetic recording medium capable of achieving high density recording. The method includes forming a metallic layer on a concavo-convex pattern formed on a surface of a mold; bonding a substrate using an adhesive to a surface of the metallic layer on the side opposite to the mold; separating the mold from the metallic layer; forming, through nanohole formation treatment, a porous layer in which a plurality of nanoholes are formed to orient in a direction substantially perpendicular to a substrate plane by using as a nanohole source a concavo-convex pattern which has been formed by transferring the concavo-convex pattern in the mold to the metallic layer; and charging a magnetic material inside the nanoholes.

The substrate (1) is made of resin. At least a part of the surfaces of the substrate 1 held in contact with the soft magnetic layer (2) has a surface roughness of no less than 4 nm, thereby improving adhesion between the substrate (1) and the soft magnetic layer (2). Since the substrate (1) is made of resin, the production cost can be reduced.

摘要： A magneto-optical recording medium (D1) includes a soft magnetic layer (2) and a magneto-optical recording layer (3) laminated sequentially onto a substrate (1) and is provided with a plurality of grooves (G) and lands (L). The product of the saturation magnetic flux density and thickness of the soft magnetic layer (2) is made different for the respective grooves (G) and lands (L). Thus, with respect to each groove (G) and each land (L), the magnetic focusing effect can be enhanced for one of these with a greater product of saturation magnetic flux density and thickness of the soft magnetic layer (2), while the effect can be weakened for the other one with a smaller product of saturation magnetic flux density and thickness of the soft magnetic layer. This enables the incidence of cross-writing to be suppressed.
