Abstract:
1. A method of magnetic transfer for magnetically transferring information represented by a pattern of a magnetic layer formed on a master information carrier to a magnetic layer of a slave medium comprising the steps of applying an initial DC magnetic field to the slave medium by a magnetic field generator to initially magnetize the magnetic layer of the slave medium in one direction of recording tracks and applying a transfer magnetic field to the slave medium and the master information carrier by a magnetic field generator in the direction opposite to the direction of the initial-magnetization with the initially-magnetized magnetic layer of the slave medium held in close contact with the magnetic layer on the master information carrier, wherein the improvement comprises that the initial DC magnetic field is applied to the slave medium with the slave medium supported from one side thereof so that the other side of the slave medium is directly opposed to the magnetic field generator, and the transfer magnetic field is applied to the slave medium and the master information carrier held in close contact with each other so that the initially-magnetized magnetic layer of the slave medium held in close contact with the magnetic layer on the master information carrier by a holder, which covers both the sides of the slave medium/master information carrier assembly, with the magnetic field generator positioned to oppose both the sides or one side of the slave medium/master information carrier assembly so that the magnetic field generated by the magnetic field generator is applied to the slave medium and the master information carrier through the holder.
