Abstract:
1. A magnetic transfer method comprising the steps of: conjoining a magnetic layer, which has been formed in a pattern for transferring data to a magnetic layer of a slave medium, of a master medium with the magnetic layer of the slave medium to form a conjoined body, and applying a transfer magnetic field to the respective magnetic layers of the conjoined master medium and slave medium to magnetically transfer the data to the magnetic layer of the slave medium, wherein said slave medium is a perpendicular magnetic recording medium, and after the magnetic layer of said slave medium has been subjected 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 direction thereof to initially magnetize said magnetic layer, the magnetic layer of said slave medium and the magnetic layer of the master medium are conjoined and a transfer magnetic field is applied to the respective magnetic layers thereof in a direction opposite that in which the initial direct current magnetization has been performed, and said conjoined body formed of the conjoined master medium and slave medium is moved relative to the transfer magnetic field, which is generated over a region that is narrower than a track region, so as to pass the entirety of the track region of said slave medium through the transfer magnetic field.
