    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.
