Abstract
The purpose of the present invention is to provide a perpendicular magnetic recording medium which uses an Ru seed layer having a (002)-oriented hcp structure, and has a magnetic recording layer including a (001)-oriented L10 ordered alloy suitable to perpendicular magnetic recording. The magnetic recording medium of the present invention includes a substrate, a first seed layer containing Ru, a second seed layer containing ZnO, a third seed layer containing MgO, and a magnetic recording layer containing an ordered alloy, in this order, the first seed layer having the (002)-oriented hexagonal closest packed structure.
