Abstract
A magnetic transfer apparatus is provided with a transfer holder. A master information carrier and a slave medium are accommodated in the transfer holder in an overlapping state where they are opposed to each other and held in close contact with each other. The master information carrier and the slave medium overlapping each other are pressed against each other by hermetically closing the holder and evacuating the inner space of the holder.
