Method and apparatus for magnetic transfer

摘要

The present invention provides a method for magnetic transfer, the method including the steps of arranging ring shape head electromagnets at least on one of upper and lower surfaces of the slave medium, rotating the slave medium or the ring shape head electromagnet in track direction, performing initial DC magnetization on the slave medium in advance in track direction by applying magnetic field in track direction on the surface of the slave medium, bringing the master carrier for magnetic transfer closely together with the slave medium processed by the initial DC magnetization, and performing magnetic transfer by applying magnetic field for transfer in track direction reverse to the direction of the initial DC magnetization on the surface of the slave medium.
