Patent ID: 7038868

Claim:
A method of magnetic transfer for magnetically transferring information represented by a pattern of magnetic layer formed on a master information carrier to a magnetic layer of a disc-like slave medium comprising the steps of applying an initial DC magnetic field to the slave medium to initially magnetize the magnetic layer of the slave medium in one direction of concentric recording tracks and applying a transfer magnetic field to the slave medium in the direction opposite to the direction of the initial-magnetization with the initially-magnetized magnetic layer of the slave medium held in close contact with the magnetic layer on the master information carrier, wherein the improvement comprises that at least one of applying the initial DC magnetic field and applying the transfer magnetic field is effected by applying the magnetic field while the slave medium is being rotated relatively to the magnetic field and stopping the rotation of the slave medium after the intensity of the magnetic field is gradually reduced to not stronger than a predetermined value, and wherein the intensity of the initial DC magnetic field is not lower than the coercive force of the magnetic layer of the slave medium.
