摘要:
A magneto-optical recording method capable of overwriting on a magneto-optical recording medium is disclosed. The magneto-optical recording medium includes a recording layer comprising a single magnetic layer with magnetic anisotropy and the magneto-optical recording methods includes the step of applying a laser beam with a light power level P.sub.1 to the recording layer when a binary coded signal "1" is written therein under a fixed external magnetic field; and the steps of applying a laser beam with a light power level Poh to the recording layer and successively applying a laser beam with a light power level Pol to said recording layer when a binary coded signal "0" is written therein under a fixed external magnetic field, wherein Pol, P.sub.1 and Poh are in the relationship of 0
