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.
