ABSTRACT:
Information represented by a pattern of a magnetic layer formed on a master information carrier is magnetically transferred to a slave. An 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 a transfer magnetic field is applied to the slave medium and the master information carrier held in close contact with each other 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 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.
