Abstract:
A method for magnetic transfer by bringing a master carrier for magnetic transfer together with a slave medium and by applying magnetic field for transfer, said master carrier having a magnetic layer formed on surface of a substrate corresponding to an information signal, and said slave medium comprising a magnetic recording medium where the information is to be transferred, said method comprising the steps of:arranging permanent magnets each magnetized symmetrically to the axis of the magnetic pole with the same polarities facing to each other and with the slave medium interposed between, and disposing the slave medium perpendicularly to the axis of the magnetic pole, rotating the slave medium or the permanent magnets in track direction; and applying magnetic field in track direction on the surface of the slave medium, whereby: after initial DC magnetization has been formed on the slave medium in advance in track direction, the master carrier for magnetic transfer and the slave medium processed by said initial DC magnetization are brought closely together, and a magnetic field for transfer in reverse direction to the direction of the initial DC magnetization on the surface of the slave medium is applied in track direction, and magnetic transfer is performed.
