Patent ID: 7477464

Claim:
A method with a process of copying prescribed information from an electro-magnetic field copy master, for manufacturing a perpendicular magnetic record medium, the copying process comprising: initializing a magnetization direction of the perpendicular magnetic record medium in a direction which is the reverse of a direction of an external electro-magnetic field; closely touching or approaching the perpendicular magnetic record medium on or to the electro-magnetic field copy master provided with a substrate which has concavity and convexity corresponding to the prescribed information on the surface and at least the convex part of which of the concavity and convexity is made of a soft magnetic material, and a conductor is provided above a concave part of the substrate wherein a lower surface of the conductor and a lower surface of the soft magnetic film on the convex part are approximately in the same plane; and instantaneously applying an external electro-magnetic field stronger than coercive field strength of the perpendicular magnetic record medium to the perpendicular magnetic record medium and the electro-magnetic field copy master.
