A magneto-optical recording apparatus which records information through the processes of: first irradiating a light beam onto a magneto-optical recording medium having a recording film; and next applying an external magnetic field that is inverted in response to a recording signal onto the recording film while continuing the first process. In the above arrangement, the intensity of the light beam is dropped upon inversion of the external magnetic field so that information is not recorded. The intensity of the light beam is raised during non-inversion of the external magnetic field so that information is recorded. Further the magneto-optical recording apparatus is provided with a light intensity control device for varying the intensity of the light beam dependent of the lengths of recording bits so that the high-temperature area of the recording film is not widened. Since the width of the recording bits is uniformly maintained, the remaining of the recording bit after overwriting operation can be reduced; thus, the signal quality in reproduction can be enhanced.
