ABSTRACT:
An optical recording media formed of a composite film the coloration of which changes when exposed to a focused laser to store multiple bits of information at a single spot. The media is formed by depositing a metal film on a substrate; oxidizing a layer of the metal film to form an amorphous film; and depositing a dielectric-like film on the amorphous film.
