Abstract
A magnetic transfer method comprises the processes of: adhering a side having a perpendicular magnetic recording layer of a perpendicular magnetic recording medium in which a perpendicular magnetic recording layer is formed on a surface of a disk shaped substrate, to a surface of a master recording medium in which a magnetic layer is formed corresponding to information to be recorded for transferring information to the perpendicular magnetic recording medium and of the side having the magnetic layer formed; and performing magnetic transfer by relatively rotating a magnetic field application device about the center of the perpendicular magnetic recording medium as an axis with respect to the perpendicular magnetic recording medium and the master recording medium, while applying a magnetic field to the perpendicular magnetic recording medium and the master recording medium by the magnetic field application device, wherein the magnetic field application device is rotated two or more times.
