Magneto-optical recording apparatus capable of erasing/writing or direct overwriting in dependence on the medium type

摘要

In recording of information, a light beam which is intensity-modulated in accordance with a recording signal is applied to a magneto-optical recording medium. A bias magnetic field is applied onto the irradiated portion of the light beam on the recording medium. It is detected whether the recording medium is an overwritable medium or not. In accordance with the detection result, the modulation condition of the light beam intensity and the direction of the bias magnetic field is changed. <IMAGE>
