A magnetic transfer apparatus for magnetically transferring information represented by a pattern of a magnetic layer formed on a master information carrier to a slave medium includes a magnet unit which applies an initial DC magnetic field to a slave medium and a magnet unit 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 with the slave medium held in close contact with the master information carrier. The initial DC magnetic field and the transfer magnetic field 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.
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
16 A magnetic transfer apparatus as defined in claim 11 in which the permanent magnet unit is provided with a third permanent magnet which is magnetized in perpendicular to the direction of magnetization of the aforesaid permanent magnets and disposed between the aforesaid permanent magnets in a direction to enhance the magnetic field between the aforesaid permanent magnets.
