Abstract:
A magnetic transfer apparatus, for magnetically transferring servo data carried by a master disc to a perpendicular magnetic recording medium comprising a substrate and a magnetic recording layer on the substrate, the magnetic transfer apparatus comprising:a positioning means for positioning the master disc in close proximity to or in tight contact with the perpendicular magnetic recording medium; an adjusting means for adjusting the positions of the master disc and the perpendicular magnetic recording medium; and a first magnetic field application means for applying a magnetic field to magnetically transfer in a perpendicular direction to the master disc and the perpendicular magnetic recording medium positioned in close proximity to each other or in tight contact with each other, wherein the first magnetic field application means includes a pair of magnetic transfer heads that position symmetrically with respect to the surface of the perpendicular magnetic recording medium facing the master disc, and wherein the magnetic transfer heads move symmetrically with respect to the surface of the perpendicular magnetic recording medium facing the master disc in opposing directions from opposite sides of the magnetic recording medium.
