Abstract
A magnetic transfer apparatus includes a holder which contains therein a master information carrier carrying thereon information to be transferred and a slave medium to which the information born by the master information carrier is to be transferred. The master information carrier and the slave medium are pressed against each other under pressure acting on the holder when the holder is evacuated, and a transfer magnetic field is applied to the slave-medium-master-information-carrier assembly. The holder includes upper and lower holder portions having flat plate portions which are brought into abutment against the other side of the slave medium or the master information carrier and are movable toward and away from each other. At least one of the flat plate portions is flexible.
