ABSTRACT:
An optical recording media having a thermally insulating film to minimize heat loss wherein the thickness of the film is not critical for recording. The thermally insulating film is disposed between a metal coated substrate and a dielectric-like film to form the optical recording media. When a spot on the dielectric-like film is exposed to a focused laser the coloration thereof changes to store multiple bits of information at a single spot.
