ABSTRACT:
A data recording method for a magneto-optical recording medium that is adapted to record a data on the magneto-optical recording medium without cross-erasing. In this method, a laser light is irradiated onto the magneto-optical recording medium to record a data. Reflective lights reflected by the magneto-optical recording medium are detected and a first and second signal are produced from the reflective lights. The intensity of a light to be irradiated onto the magneto-optical recording medium is controlled on the basis of the third signal. The third signal is obtained by the operation of the first and second signals.
