    摘要: In reading a magneto-optical recording medium comprising a substrate and a magnetic multilayer on a surface of the substrate, which multilayer comprises, in order from the surface of the substrate, an amplifying layer A.sub.1, a control layer C.sub.2, and a recording layer R.sub.3 with a magnetic domain formed therein, the medium is first irradiated with a laser beam while a reading magnetic field is applied thereto in one direction. With the resulting temperature increase, the magnetic domain in R.sub.3 is successively copied from C.sub.2 to A.sub.1 to form copied magnetic domains, which are in turn enlarged by a reading magnetic field. Then, the enlarged, copied magnetic domain in A.sub.1 is read out. Thereupon, laser beam irradiation is interrupted or the power of the laser beam is decreased to thereby vanish the copied magnetic domains in A.sub.1 and C.sub.2. To carry out reading by light intensity modulation, an interface wall exchange force magnetic field between the respective magnetic layer, etc. is controlled, so that reading can take place with no application of a modulated magnetic field.
