Unit Record Card Graphic Techniques.
Abstract
Work during the first six months of an 18-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 readily stored on and retrieved from a 3-inch 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 at 220 cycles per millimeter with about half the desired deformation amplitudes obtained thus far. Also described are the design and tests with an Electrofax copy maker of a special recorder/processor/projector unit. (Author)
