An optical information storage medium has multiple information layers. On each layer, 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.

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

A multilayer optical information storage medium, such as a card, uses a luminescent, fluorescent, or electroluminescent material to reproduce information in the form of incoherent radiation. Each layer has multiple pages of information. A specific page on a specific layer is addressed by moving the card relative to a read head so that the image of the specific page to be read is focused on the read head. This can be accomplished by moving the card in the X, Y, and Z directions, or by holding the card stationary and by moving a two-dimensional image detector in the X, Y, and Z directions.
