Abstract:
A magneto-optical recording medium for an optical system having a ratio of wavelength to numerical aperture of lens being not more than about 1000 nm, the magneto-optical recording medium comprising:a first light transmitting dielectric layer to a first surface of which the light strikes; a magneto-optical recording layer formed on a second surface opposed to the first surface of the first dielectric layer; a light transmitting metal layer formed on the magneto-optical recording layer having a larger heat conductivity than the magneto-optical recording layer; a second light transmitting dielectric layer formed on the light transmitting metal layer; and a metal reflective layer formed on the second dielectric layer and reflecting layer, wherein the thickness of the light transmitting metal layer is not less than about 10 nm and not more than about 60 nm.
