The present invention provides a magnetic transfer master carrier which forms a magnetic pattern corresponding to a pattern of information to be recorded on a perpendicular magnetic recording medium when a magnetic field is applied to the perpendicular magnetic recording medium, with the magnetic master carrier and the perpendicular magnetic recording medium closely attached to each other, the carrier including: a base material having convex portions on its surface, the convex portions being provided corresponding to the pattern of information; a magnetic layer deposited on at least top surfaces of the convex portions, and having perpendicular magnetic anisotropy; and a soft magnetic layer deposited on the surface of the magnetic layer.

Magnetic transfer master carrier, magnetic transfer method, and magnetic recording medium

A magnetic transfer master carrier of the present invention includes a base material having convex portions on its surface, the convex portions being provided corresponding to a pattern of information to be recorded on a perpendicular magnetic recording medium, and a magnetic layer deposited at least on top surfaces of the convex portions, wherein when a magnetic field is applied to the magnetic transfer master carrier, the magnetic layer absorbs a magnetic flux so as to form a pattern of the magnetic field, wherein the magnetic layer includes at least two perpendicular magnetic anisotropic layers, and an antiferromagnetic coupling induction layer which is provided so as to be sandwiched in between two neighboring layers of all the perpendicular magnetic anisotropic layers, and to induce antiferromagnetic coupling therebetween.
