Vertical magnetic recording medium, magnetic recording apparatus and manufacturing method of a vertical magnetic recording medium

摘要

A vertical magnetic recording medium includes a substrate, a soft magnetic backing layer formed on the substrate, a magnetic flux confinement layer formed on the soft magnetic backing layer, an intermediate layer formed on the magnetic flux confinement layer, and a recording layer of a vertical magnetization film formed on the intermediate layer. The magnetic flux confinement layer has a plurality of soft magnetic parts each formed along a track region of plural track regions and a non-magnetic parts formed between adjacent track regions. The intermediate layer is formed of a non-magnetic material and is formed so as to cover a surface of the soft magnetic part and the non-magnetic parts.
