ABSTRACT:
A magneto-optical recording device includes a magnetic field generating coil for generating a magnetic field on a magneto-optical recording medium, a power source for supplying a current to the magnetic field generating coil, switching circuit for driving said magnetic field generating coil to supply the current from the power source in the positive and negative directions by alternately forming first and second current paths according to recording information, first correcting circuit which is disposed on the first current path for correcting a transient response of the current amplitude in the positive direction caused by the magnetic field generating coil, and second correcting circuit which is provided on the second current path for correcting a transient response of the current amplitude in the negative direction caused by the magnetic field generating coil.
