LM, PLASTICS), GRAPHICS, RECOVERY, RESOLUTION, WEAR RESISTANCE, OPTICS, PHOTOGRAPHIC IMAGES, DIFFRACTION GRATINGS, PHOTOGRAPHIC PROCESSORS, REPRODUCTION*PHOTOPLASTIC RECORDING SYSTEMS, DRY PHOTOGRAPHIC PROCESSINGWork during a 20-month program to develop graphical techniques for a unit record card based on photoplastic film is described. The unit record card will ultimately permit a combination of machine-readable characters, man-readable characters, and high-density graphic material (such as engineering drawings and photographs) to be stored readily on and retrieved from a reusable 3- by 5-inch card. Photoplastic film is a photoconductive, thermoplastic, recording film which permits rapid dry development, add-on capability, and reuse. The work includes efforts to optimize film performance and produce a quantity of cards and design, construction, and testing of equipment to record, process, project, duplicate, produce hard copy facsimiles from, and erase these cards. Tests are described showing that major performance goals were met. (Author)
