ABSTRACT:
A magneto-optical recording device having a light source and external magnetic field applying apparatus, which records information on a magneto-optical recording medium with a magnetic field modulation method. The device has a controller which stops the irradiation of a light beam when switching the direction of applying external magnetic field during recording. This allows an area where information is recorded with a low external magnetic field to be smaller, and thereby achieving reproduced signal of improved quality.
