ABSTRACT:
An apparatus for recording, reproducing and erasing data or information on a magneto-optical recording medium, for applying a steady magnetic field to the recording medium and for applying a variable magnetic field, a portion of the apparatus for applying the magnetic field being integrated into a recording head and and the record head being disposed on different sides of the recording medium, this results in the miniaturization of the means for applying the magnetic field to the recording medium and the apparatus presents an excellent recording/erasure property.
