Abstract
A multilayer, direct-overwrite, magneto-optic recording elment comprises first and second layers of magnetic materials having different magnetic coercivities and Curie temperatures. Such layers are spaced apart by an intermediate layer comprising a readily polarizable non-magnetic metal. The intermediate layer serves to control the degree of magnetic exchange interaction between the magnetic layers, and prevents the constituents of the magnetic layers from diffusing between such layers.
