ABSTRACT:
In a magnetooptical recording apparatus, a magnetic field modulated in accordance with an input signal is applied to a portion of a recording medium onto which a light beam is irradiated. The magnetooptical recording apparatus includes a device for applying a magnetic field for canceling a self leakage magnetic field applied from a portion having a magnetization other than the light beam irradiated portion of the medium, and a leakage magnetic field leaking from a member other than the medium.
