Patent ID: 6867935

Claim:
A magnetic transfer apparatus for magnetically transferring information represented by a pattern of a magnetic layer formed on a master information carrier to a magnetic layer of a slave medium comprising an initial magnetization means which applies an initial DC magnetic field to a disc-like slave medium while rotating the slave medium relatively to the initial DC magnetic field to initially magnetize the magnetic layer of the slave medium in one direction of concentric recording tracks thereof and a transfer magnetic field application means which applies a transfer magnetic field to the slave medium and the master information carrier in the direction opposite to the direction of the initial-magnetization while integrally rotating the slave medium and the master information carrier relatively to the transfer magnetic field 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 the initial DC magnetic field and the transfer magnetic field respectively applied by the initial magnetization means and the transfer magnetic field application means are not larger than the diameter of an innermost recording track in the half-width of a curve representing an intensity distribution in the direction of a tangent of the innermost recording track on the surface of the slave medium.
