ABSTRACT:
Disclosed is a magnetic transfer apparatus capable of performing good magnetic transfer, including a holder for accommodating a master carrier with transfer patterns corresponding to transfer information, a slave-feeding unit for feeding a slave medium with a magnetic recording part to be transferred to the master carrier, and a magnetic field application unit for applying a magnetic field in a state that the slave medium is in close contact with the master carrier, wherein the holder is provided with a slave holding shaft for positioning a central opening of the slave medium at a central portion thereof, and an inner diameter of the central opening of the slave medium is set to be smaller than that of a central opening the master carrier, and the slave-feeding unit holds an inner diameter portion of the slave medium. The inner diameter portion of the slave medium fed to the master carrier is sucked by use of suction grooves, and the slave medium is preferably brought into temporary contact with the master carrier.
