Electroluminescent multilayer optical information storage medium with integrated readout and composition of matter for use therein

An optical information is stored in the form of an electroluminescent material. The pits are organized into regions called pages. A specific page on a specific layer can be addressed through electrodes integrated into the medium. The medium can be read-only or WORM. For the WORM embodiment, a record...

More Information
Summary:An optical information is stored in the form of an electroluminescent material. The pits are organized into regions called pages. A specific page on a specific layer can be addressed through electrodes integrated into the medium. The medium can be read-only or WORM. For the WORM embodiment, a recordable electroluminescent material is combined with a quencher and a free radical generating compound that, when thermally degraded, generates free radicals to bleach the quencher. To amplify the light from an information layer, a photoconductive layer and an additional electroluminescent layer can be provided.
