Claim 1
Independent Claim
177 words
A HOLOGRAPHIC MEMORY SYSTEM, COMPRISING A MULTI-LAYER HOLOGRAPHIC STORAGE DEVICE INCLUDING A TRANSPARENT THERMOPLASTIC RECORDING MEDIUM HAVING A LARGE AREA FOR THE STORAGE OF A LARGE NUMBER OF INDIVIDUAL HOLOLGRAMS, A PHOTOCONDUCTIVE LAYER, AND AT LEAST ONE LAYER PROVIDING LIGHT ADSORPTION, ELECTRICAL CONDUCTIVITY AND PHYSICAL SUPPORT, MEANS TO HEAT THE ENTIRE AREA OF SAID THERMOPLASTIC STORAGE MEDIUM TO A TEMPERATURE JUST BELOW THE TEMPERATURE AT WHICH SAID MEDIUM BECOMES PLASTIC, MEANS TO PLACE A UNIFORM ELECTRIC CHARGE ON SAID THERMOPLASTIC RECORDING MEDIUM, AND MEANS TO DIRECT AN 0BJECT BEAM AND A REFERENCE BEAM FORMING AN INDIVIDUAL HOLOGRAM TO AND THROUGH A SINGLE SELECTED SMALL AREA OF SAID STORAGE MEDIUM AND SAID PHOTOCONDUCTOR, WHEREBY AN ELECTRICALLY CONDUCTIVE PATTERN IS FORMED IN SAID PHOTOCONDUCTIVE LAYER WHICH RESULTS IN A CORRESPONDING CHARGE PATTERN THEREON, SAID OBJECT BEAM AND REFERENCE BEAM CONTINUING ON TO SAID LIGHT ABSORPTION LAYER, WHEREBY HEAT GENERATED IN SAID LIGHT ABSORPTION LAYER CAUSE SOLELY SAID SMALL AREA OF SAID RECORDING MEDIUM TO BECOME PLASTIC, SO THAT IT CAN ASSUME A PHYSICAL PATTERN DETERMINED BY SAID CHARGE PATTERN.
Claim 2
Dependent Claim

Claim 5
Dependent Claim
18 words
A holographic memory system as defined in claim 1 wherein said layer providing light absorption includes black gold.
Claim 6
Dependent Claim
18 words
A holographic memory system as defined in claim 2 wherein said layer providing light absorption includes black gold.
Claim 7
Dependent Claim
35 words
A holographic memory system as defined in claim 1 wherein said means to heat the entire area of the thermoplastic recording medium comprises means to pass an electric current through said layer having electrical conductivity.
