Abstract
A magnetic transfer apparatus capable of enhancing the quality of a transfer signal by improving close contact property between master and slave media in magnetic transfer carried out to magnetically transfer an information signal such as a servo signal from the master medium to the slave medium. In the magnetic transfer specifically carried out by applying a transfer magnetic field in a close contact state of the master medium bearing information and the slave medium, the master and slave media are closely contacted with each other in a state where the backside of the master medium is adsorbed and held on the flat adsorbing surface of an adsorbing member to heighten the flatness of the master medium. In the case of one-surface transfer, preferably, an elastic body is closely contacted with the surface opposite to the master medium on the slave medium.
