録装置。 A recording medium including a magnetic thin film having perpendicular magnetization, an optical head that applies a minute spot of laser light to the recording medium, and a magnetic field application that applies a magnetic field to the recording medium film surface when writing or erasing information on the recording medium. In the magneto-optical recording device, the magnetic field applying device includes a magnetic flux generating device having a magnetic pole in a movable direction, and a means for causing the magnetic field applying device to respond to the optical head by disposing the magnetic field applying device in a movable direction. A first magnetic field that passes through the recording medium from the top surface to the bottom surface obtained by the generating means and a second magnetic field that passes through the recording medium from the bottom surface to the top surface are generated by the laser beam from a minute spot of the optical head. 1. A magneto-optical recording device comprising means for moving the irradiated area to the irradiated area.
