Abstract
A magnetic transfer apparatus includes an inexpensive and small adjusting mechanism for adjusting the positions of the magnetic heads, that facilitates preventing anomaly of drastically changing transferred signal intensity, and a very rigid mounting mechanism for mounting the magnetic heads. The magnetic transfer apparatus includes a magnetic field application means for magnetic transfer, the magnetic field application means applying a magnetic field to the master disc and the perpendicular magnetic recording medium positioned in tight contact with each other or in close proximity to each other, the magnetic field application means including a pair of magnetic heads for magnetic transfer positioned symmetrically with respect to the surface of the perpendicular magnetic recording medium facing to the master disc, the magnetic heads moving always keeping their symmetrical positional relation ship with respect to the surface of the perpendicular magnetic recording medium facing to the master disc.
