Title:
ELECTROLUMINESCENT OPTICAL RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO2004109669
Kind Code:
A3
Abstract:
An optical memory device comprising a stack of layers with a first electrode layer; an electroluminescent layer, a second electrode layer opposite of said first electrode with respect to said electroluminescent layer, and a photo inducible conductor arranged between said electroluminescent layer and one of said first or second electrodes. Further a method of forming a recording structure in such an optical recording medium is proposed. Further, systems for recording and reproducing information stored on such an optical memory device are proposed. In the system for reproducing information an incident light beam induces increased conductivity in said photo inducible conductor layer and light emitted from said electroluminescent layer in response to said incident light beam is directed onto a detector. In the system for recording information an incident light beam suitable for degrading said photo inducible conductor layer material and/or said electroluminescent layer material is generated.
