Magnetooptischer Aufzeichnungsträger

摘要

A magneto-optical recording medium is obtained by consecutively forming on a substrate (1) a ground layer (2) and a perpendicular magnetic recording layer (3) being a synthetic lattice film formed by alternately laminating two or more combinations of Co layer and Pt layer, which is characterized in that the ground layer (2) is made of a material selected from the group consisting of composite oxides containing Y, Ba and Cu, TiC, Nb2O5, Si, intermetallic compounds between Si and a metal, SiC, SrTiO3 and CeO2.
