Abstract
A system and method for magnetic transfer. A magnetic transfer device includes a plurality of pairs of magnetic field generating units that apply a magnetic field to a contact body which includes a master disk in close contact with a magnetic recording medium, wherein the master disk has a pattern of preformatted signals. The magnetic field generating units, falling within a specified length range, are moved in synchrony at a predetermined speed in the directions of the outer periphery while the contact body is caused to rotate by a rotation drive unit. The system and method provide a magnetic transfer method and a magnetic transfer device that, by reducing the area of magnetic field generating units that apply a transfer magnetic field, can reduce an attractive force (or repulsive force) between the magnets, and furthermore, shorten a processing time for the transfer.
