摘要：
To provide a magnetic transfer master carrier to be placed on a perpendicular magnetic recording medium so as to transfer magnetic information to the medium by application of a magnetic field, the magnetic transfer master carrier including: transfer portions that include a magnetic layer and correspond to the magnetic information; and non-transfer portions which are lower in height than the transfer portions that include the magnetic layer, and each of which has a concave shape, wherein the magnetic layer has perpendicular magnetic anisotropy, and the magnetic anisotropy energy of the magnetic layer is less than 4×106 erg/cm3.
