ABSTRACT:
According to the present invention, a light beam is radiated to an area between recording tracks while the intensity of a magnetic field from the outside to a magneto-optical recording medium is suppressed to 50 Oe or less, whereby magnetic anisotropy formed between the recording tracks is set to be lower than that of the magnetic layer on the recording tracks, and micro-domains, for example, having a diameter smaller than a half-width of a light beam for reproduction in a film surface direction are formed on recording tracks. Because of this method, the influence of a leakage magnetic field in the magneto-optical recording medium adopting a DWDD reproducing system is alleviated.
