Abstract:
1. A magnetic recording medium comprising: a substrate; a soft magnetic layer formed over the substrate; a recording layer formed over the soft magnetic layer such as to have magnetic anisotropy in a direction perpendicular to surface, and being divided in a number of recording elements by a predetermined concavo-convex pattern; and an intermediate layer formed between the recording layer and the soft magnetic layer, wherein the recording elements are formed to have a predetermined shape of tracks in a data region, the recording elements extend continuously over entire width of the tracks, concave portions of the concavo-convex pattern are formed to a midway in a thickness direction of the intermediate layer, the recording layer is divided by the concave portions through to a face on a side of the substrate, the intermediate layer is continuous on a face on the side of the substrate, the concave portions of the concavo-convex pattern are not formed in the soft magnetic layer, the soft magnetic layer is a continuous film, and the magnetic recording medium does not comprise any soft magnetic film in which the concave portions of the concavo-convex pattern are formed.
