Description

ABSTRACT:
A magneto-optical recording medium comprises a substrate and provided thereon a magneto-optical recording layer and a protective resin layer, a magnetic field being applied to the magneto-optical recording layer from the side of the protective layer by a magnetic-field generating means, and the recording layer being irradiated with a light beam through the substrate to record information. The protective layer has a first surface confronting the magnetic-field generating means and a second surface confronting the recording layer, and the protective layer has a surface resistivity of 1.times.10.sup.10 .OMEGA./.quadrature. or less on the first surface and has a region with a thermal conductivity of 10 W/m.multidot.K or less, extending from the second surface toward the first surface.
