ABSTRACT:
The present invention provides a magnetic transfer method comprising: a magnetic transfer step of applying a magnetic field for transfer parallel to the plane of a disk shaped substrate having formed on the surface thereof a pattern composed of magnetic layer arrangement corresponding to information to be transferred to a perpendicular magnetic recording medium while a master recording medium for perpendicular magnetic transfer being the substrate is brought into close contact with the perpendicular magnetic recording medium, and thereby transferring the magnetic pattern of the master recording medium for perpendicular magnetic transfer to the perpendicular magnetic recording medium; and a servo correction information writing step of writing by use of a magnetic head, servo correction signal information into a section adjacent to the information transferred to the perpendicular magnetic recording medium by the magnetic transfer step.
