A magneto-optical recording medium for MSR reproduction of a high signal quality wherein both faces of a land and a groove are used as recording tracks is disclosed. A magneto-optical recording medium wherein both of a land portion and a groove portion on a substrate are used as recording and reproduction tracks while laser light having passed through an objective lens is illuminated on the recording and reproduction tracks is configured that a ratio Wg/Wl between a track width (Wg) of the groove portion and a track width (Wl) of the land portion is equal to or higher than 0.65 but equal to or lower than 0.85, and, where the wavelength of the laser light is represented by ", the numerical aperture of the objective lens by NA and the refractive index of the substrate by n, the groove distance Gp is equal to or greater than 1.0 x "/NA but equal to or smaller than 1.2 x "/NA and besides the depth D of the groove is equal to or greater than "/11n but equal to or smaller than "/8n.
