摘要：
A magnetic transfer master substrate for transferring magnetic information thereof to a perpendicular recording magnetic recording medium in contact therewith under application of a magnetic field comprises a transfer surface area with a magnetic layer formed thereon in a pattern according to the magnetic information to be transferred to the perpendicular magnetic recording medium and a non-transfer surface area laying below said transfer surface area, wherein the magnetic layer has a perpendicular magnetic anisotropy of an anisotropy energy higher than 4×106 erg/cm3.
