Abstract
A recording medium for reflective readout in an optical information recording system. The medium comprises a substrate such as PET or PMMA on emulsion layer of silver halide material and an optical protective layer. The emulsion is exposed to a laser source to form a latent data image and is then developed to exhibit a glossy silver metallic image. Playback uses established systems.
Claims6
A method of optical data recording comprising the steps of, exposing a silver halide emulsion layer to modulated optical data by light focused by a focusing lens to form a latent image and developing said silver halide emulsion layer to form a reflective glossy metallic silver image having a light reflection greater than 10% on portions where said latent image exists.
