Abstract

A magneto-optical recording disk has a transparent resinous substrate with a pre-groove, and a metallic recording layer formed above the substrate. A transparent adhesive layer is provided between the substrate and the recording layer, for allowing a laser beam to pass therethrough, and for causing the recording layer to be tightly adhered to the substrate to thereby prevent the recording layer from being peeled off from the substrate. The adhesive layer is comprised of a fluorine resin material.
