Magneto-optical recording apparatus

A magneto-optical recording apparatus for recording information on a magneto-optical recording medium composed of a substrate, a memory layer and a recording layer which are disposed on the substrate, each of the memory and recording layers being comprising a magnetic thin film of amorphous-rare-earth transition-metal alloy, the memory and recording layers being magnetically coupled directly, or through an intermediate layer therebetween, to each other under an exchange force, said magneto-optical recording apparatus comprising:

• recording magnetic field generating means for applying a recording magnetic field to the magneto-optical recording medium;
• and
• initializing magnetic field generating means for applying an initializing magnetic force to the magneto-optical recording medium, said initializing magnetic field generating means having a magnetic pole adapted to be disposed in confronting relationship to a surface of the magneto-optical recording medium, said initializing magnetic force comprising a magnetic field H.sub.V directed perpendicularly to the surface of the magneto-optical recording medium, and a magnetic field H.sub.H directed along the surface of the magneto-optical recording medium, said magnetic fields H.sub.V, H.sub.H being defined as follows:
• H.sub.V.ltoreq.H.sub.C2 +H.sub.W2,
• and
• H.sub.H >{(H.sub.C2 +H.sub.W2)-H.sub.V }.times.1.7
• where H.sub.C2 is the coercive force of the recording layer and H.sub.W2 is the exchange force.
