A magnetic transfer wherein the exchange of master mediums is made easy to perform is provided, whereby the operational efficiency and transfer efficiency are improved, leading to an overall improvement in productivity in the manufacture of preformatted slave mediums. A master fixing base for determining and supporting the position of a master medium, which bears transfer data, and a conjoining apparatus for conjoining the master medium and the slave medium that is to receive the transfer therefrom are provided. The master medium is exchanged along with the master fixing base. It is preferable that a cleaning means be provided.

Method and apparatus for magnetic transfer

A magnetic transfer device for bringing a master carrier with information and a slave medium into intimate contact with each other and then applying a transfer field to transfer the information to the slave medium. The master carrier has an inclined face on its radially outer end. After the magnetic transfer of the information, claws are inserted in the gas formed by the inclined face of the master carrier and the slave medium. The slave medium held in intimate contact with the master carrier is separated from the master carrier by lifting the slave medium with the claws.

Magnetic transfer device

In magnetic transfer performed to transfer an information signal such as a servo signal from a master medium to a slave medium, the degradation of transfer quality caused by a failure of close contact between the master medium and the slave medium due to dust accumulated thereon is prevented. Magnetic transfer means is provided to carry out the magnetic transfer by bringing the master medium bearing information and the slave medium into close contact with each other, and applying a transfer magnetic field. Replacing means is provided to prepare a plurality of master media, and replacing the master medium after magnetic transfer is performed a predetermined number of times. Cleaning means is also provided to clean the replaced master medium by ultrasonic washing or the like.
