ABSTRACT:
In a magneto-optical recording apparatus wherein a beam of light is irradiated upon a face of a recording medium while a magnetic field is applied to the other face of the recording medium at a location where the light beam is irradiated, production of control pulses for controlling the magnetic head so as to prevent, upon high speed recording, the magnetic head from being turned on before a terminal voltage of the magnetic head drops sufficiently to a predetermined power source voltage because the transfer rate of a recording signal is high and the reversal interval of the recording signal is short.
