To provide a magnetic head drive circuit or a magneto-optical recording device used with the circuit including a pair of auxiliary coils and a magnetic field generating coil for generating a magnetic field by alternately receiving electric currents flowing in opposite directions through the pair of auxiliary coils, and recording an information signal. When the recording of an information signal is stopped, a current for recording an information signal is maintained in a flowing state and gradually reduced, thereby shifting the recording toward a stop state. Thus, the voltage generated in the auxiliary coil by electromagnetic induction when the recording is stopped is reduced, the consumption of electric power is reduced, and the recording speed is improved.
