ABSTRACT:
A magneto-optical recording medium provided with a first dielectric layer formed on a substrate, a second dielectric layer containing at least silicone nitride and formed on the first dielectric layer, and a recording layer consisting of a magnetic film with a Curie temperature of the 200.degree. C. or higher and formed on the second dielectric layer. This magneto-optical recording medium is characterized in that the thermal conductivity of the first dielectric layer is smaller than that of the second dielectric layer.
