PROBLEM TO BE SOLVED: To prevent deterioration of the transfer quality due to the defective tight adhesion between a master carrier 3 and a slave medium 2 caused by the sticking of dust when the magnetic transfer of an information signal like a servo signal is performed on the slave medium 2 from the master carrier 3. SOLUTION: When the magnetic transfer is performed by tightly adhering the slave medium 2 with the master carrier 3 carrying the information by a magnetic transfer means 11 to impress the magnetic field for transfer, the plural master carriers 3 are prepared, and after the magnetic transfer is performed by the specified number of times, the master carriers 3 are exchanged by an exchanging means 12 and cleaned with the ultrasonic washing, etc., by a cleaning means 13.
