ABSTRACT:
A magneto-optical recording apparatus records information in a magneto-optical recording medium with a light beam and an external magnetic field. The magneto-optical recording apparatus includes a light beam radiating device for radiating a light beam to the recording medium, an external magnetic field applying device for applying an external magnetic field modulated depending upon recording information to a portion thus radiated by the light beam, and an information reproducing device for reproducing the information recorded in the recording medium by detecting reflection light of the light beam from the medium, then to output a reproduction signal. The magneto-optical recording apparatus further includes either a detecting device for detecting whether a level of the reproduction signal is in an increase trend or in a decrease trend or a comparing device for comparing a level of the reproduction signal with a first reference value and with a second reference value. A judging device judges whether the information is correctly recorded based either on a detection result of the detecting device and a direction of the magnetic field or on a comparison result of the comparing device and the recording information.
