A magneto-optical recording method employs a magneto-optical recording medium having a first magnetic layer which exhibits low coercive force at room temper- ature and high Curie temperature and a second magnetic layer which is exchange-coupled to the first magnetic layer and which exhibits a higher coercive force and a lower Curie temperature as compared with those of the first magnetic layer. A magnetic field modulated in accordance with information to be recorded is applied to the magneto-optical recording medium while irradiating it with a light beam of a constant intensity so as to record the information. The recorded information is simultaneously confirmed by using a reflected light of this light beam.
