Magneto-optical recording medium and method for production thereof
Abstract:
A magneto-optical recording medium has on the substrate a recording layer made of a multi-layered metallic thin film comprising a first unit layer and a second unit layer. The first unit layer is composed of (Fe.sub.x Co.sub.1-x).sub.1-y M.sub.y where M represents at least one metal selected from the group consisting of Pt, Pd and Au, 0.5.ltoreq..times..ltoreq.1.0, and 0.01.ltoreq.y.ltoreq.0.1. The second unit layer is composed of a% least one metal selected from the group consisting of Nd, Dy, Gd and Tb. The first and second unit layers are superimposed alternately one on another.
