METHOD FOR OPTICAL RECORDING OF INFORMATION IN A DIGITAL SYSTEM

摘要

A recording medium for reflective readout in an optical information recording or playback system. The medium comprises a substrate such as polyethylene terephthalate or polymethyl methacrylate, an emulsion layer of silver halide material and an optional 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 establshed systems.
