ABSTRACT:
In a magneto-optical recording element comprising a substrate, a magnetic layer and a dielectric layer, the dielectric layer is formed by deposition of a composition comprising Si.sub.3 N.sub.4 and a refractive index-improving agent such as Al.sub.2 O.sub.3 or Y.sub.2 O.sub.3. This dielectric layer has a high refractive index and the enhancement effect is improved. Moreover, this dielectric layer is excellent in the adhesion and resistance characteristics.
