ABSTRACT:
An apparatus for recording an input signal on a magneto-optical recording medium. The apparatus includes an optical head for applying a light beam to the medium, a circuit for delaying the input signal by a time for preventing a bit recorded on the medium from shifting relative to the input signal, a magnetic head for applying a magnetic field modulated in conformity with the delayed signal to that portion of the medium to which the light beam is applied, and a motor for moving the medium relative to the light beam.
