<p>A vertical magnetic recording medium enabling information recording/reproduction with high-recording density and having a soft magnetic backing layer that enables low-noise recording, can be thin, and is excellent in corrosion resistance and its manufacturing method are disclosed. The vertical magnetic recording medium (10) having a soft magnetic backing layer (12) and a vertical recording layer (13) so formed on the soft magnetic backing layer (12) as to serve as a main recording layer and having an easy-magnetization axis mainly oriented vertically to the film surface is characterized in that the soft magnetic backing layer (12) characterized by being made of a soft magnetic material having a composition of FeTaN and its manufacturing method are the solving means.</p> |
