Patent ID: 7054082

Claim:
A magnetic transfer method comprising the steps of: performing an initial magnetization process on a magnetic recording layer of a high-density magnetic recording medium comprising a substrate, a first magnetic layer formed on the substrate, a nonmagnetic coupling layer formed on the first magnetic layer, and a second magnetic layer of which the coercive magnetic force is larger than that of the first magnetic layer, formed on the nonmagnetic coupling layer, to uniformly initially magnetize the first and the second magnetic layers of said high-density magnetic recording medium magnetic layer so that the respective magnetization directions thereof are oriented mutually antiparallel, and performing a transfer process of conjoining the magnetic recording layer of the high-density magnetic recording medium, which has been initially magnetized, with a magnetic layer, which is formed in a pattern corresponding to the data to be transferred to the magnetic recording layer of the high-density magnetic recording medium, of a magnetic transfer master medium, to form a conjoined body, and applying a transfer magnetic field to the conjoined body in the direction opposite the magnetization direction of the second magnetic layer to magnetically transfer the pattern corresponding to the data, wherein the initial magnetization process consists of applying a first magnetic field of a magnitude greater than or equal to the saturation magnetic field of the first and second magnetic layers, and then applying a second magnetic field, which is of a magnitude that inverts the magnetization of the first magnetic layer and does not have an effect on the second magnetic layer, in the direction opposite that of the first magnetic field.
