When a master medium and a slave medium are brought into close contact and a transfer magnetic field is applied thereto to perform magnetic transfer, the leakage magnetic field intensity of the transfer magnetic field is regulated to within a permissible range, making possible the transfer of an exact magnetic pattern. After a magnetic field is applied to the slave face in the track direction thereof to initially magnetize the slave medium in the track direction, the master medium and the slave medium are brought into close contact. When applying a transfer magnetic field in the track direction of the slave face to perform a magnetic transfer, the magnetic field intensity component in the direction opposite that in which the transfer magnetic field is to be applied is regulated to less than or equal to ½ the magnetic coercive force Hcs of the slave medium over the entire slave surface.
A magnetic transfer method comprising the steps of,
A magnetic transfer apparatus that brings into close contact a magnetic transfer master medium, which is formed of a substrate and a magnetic layer formed on the portion thereof corresponding to the data signal of the surface of the substrate, and a magnetic recording medium, which is a transfer receiving slave medium, and applies to the conjoined body formed thereby a transfer magnetic field to perform a magnetic transfer, comprising
A magnetic transfer method comprising the steps of,
