Disclosed is a magnetic transfer method magnetically transferring
information signals such as servo signals from a master medium to a slave
medium, which is capable of preventing the occurrence of missing signals
due to insufficient contact of the master medium and the slave medium
originating from adhering of dust to the slave medium, thus increasing
reliability. When the master medium bearing information signals and the
slave medium are brought into close contacted with each other, and when a
transfer magnetic field is applied to the master medium and the slave
medium to magnetically transfer the information signal from the master
medium to the slave medium, a metal thin film formed on a substrate of the
master medium is electrically grounded, and charges of the master medium
are removed, thus reducing a quantity of adhering dust.
