Abstract
A magnetic transfer apparatus including a holder for accommodating a slave medium subjected to transfer of information and master carriers bearing an information to be transferred which are to be kept in the state of being sucked to pressure-reducing suction parts of an inner surface of the holder for mutual close contact of surfaces of the slave medium and the master carriers, a vacuum suction unit for providing a vacuum condition of the inner space, and a magnetic field application unit for applying a transfer magnetic field to the holder. At the time of performing the magnetic transfer, the pressure of the inner space of the holder by the vacuum suction unit is set higher than the suction pressure of the pressure-reducing suction parts by 1-50 kPa, whereby before mutual contact of the slave medium and the master carriers, a suction state of the master carriers is kept constant.
