Magneto-optical recording apparatus having paired devices for applying external magnetic fields |
摘要 |
A magneto-optical recording apparatus of the present invention is provided with an objective lens for focusing a light beam onto a magneto-optical recording medium. A pair of magnets is disposed on opposite sides of the magneto-optical recording medium and apply a writing magnetic field onto a portion of the magneto-optical recording medium that has been irradiated by the light beam while applying an initializing magnetic field greater than the writing magnetic field onto a portion apart from that irradiated by the light beam.
