Claim 1
Independent Claim
179 words
A SHEET-LIKE STORAGE MEDIUM ADAPTED TO (A) DEVELOP THEREIN AN IMAGE PATTERN CORRESPONDING TO INFORMATION ASSOCIATED WITH A MODULATED ELECTRON BEAM WHEN SUCH A BEAM SCANS ONE FACE THEREOF DURING A RECORDING OPERATION, (B) DISSIPATE ELECTRONS DURING SUCH AN ELECTRON BEAM SCANNING OPERATION, SAID DISSIPATION BEING AT A RATE SUFFICIENT TO MAINTAIN THE ELECTROSTATIC POTENTIAL ASSOCIATED THEREWITH IN SAID MEDIUM AT A LEVEL WHICH SUBSTANTIALLY DOES NOT ADVERSELY AFFECT THE RECORDED IMAGE, (C) BE PROCESSED AFTER SUCH RECORDING OPERATION AND BEFORE READOUT BY CONVENTIONAL OPTICAL TRANSMISSION TECHNIQUES SO THAT THE IMAGED AREAS SELECTIVELY MODULATE TRANSMITTED LIGHT, SAID MEDIUM COMPRISING IN COMBINATION (A'') AN OPTICALLY CLEAR, DIMENSIONALLY STABLE, BASE SUPPORT LAYER HAVING OPPOSED PARALLEL ANCHORABLE FACES, (B'') AN ELECTRON SENSITIVE LAYER COMPOSED OF AN ELECTRON SENSITIVE COMPOSITION WHICH, WHEN DEPOSITED IN A LAYERED FORM UPON AN INERT SURFACE IS CHARACTERIZED BY HAVING THE CHEMICAL CAPACITY TO DEVELOP AN OPTICAL DENSITY OF AT LEAST ONE WHEN EXPOSED TO NOT MORE THAN 1014 ELECTRONS PER SQUARE CENTIMETER OF LAYER SURFACE AREA, SAID ELECTRONS ACCELERATED TO PENETRATE SUBSTANTIALLY ALL OF THIS SENSITIVE LAYER,
