Patent ID: 7079335

Claim:
A magnetic transfer apparatus for applying a transfer magnetic field to a conjoined body formed of a magnetic transfer master medium having a magnetic layer formed in a pattern for transferring data to a slave medium, and the slave medium is provided with a magnetic layer, to magnetically transfer said data to the magnetic layer of the slave medium, said apparatus comprising: an initial magnetizing means for subjecting the magnetic layer of the slave medium to an initial magnetization process comprising applying an initial direct current magnetic field to said magnetic layer unidirectionally in a direction perpendicular to a track surface thereof to initially magnetize said magnetic layer unidirectionally in the direction perpendicular to said track surface, and a transfer magnetic field applying means for generating a transfer magnetic field across a region narrower than the track surface of the slave medium, wherein the transfer magnetic field applying means has a width larger than that of a track having the largest radius, in a direction opposite that in which the initial direct current magnetization has been performed.
