Magnetic tape base materials possess inadequacies in certain critical data storage applications. The objective of the project is to develop backing materials which will improve the efficiency and reliability of automatic data processing equipment and astroelectronic recording devices. Evaluations of weave construction and continuous production processes for a promising new fabric were initiated. Investigation of a new polycarbonate elastomer as a resin binder commenced. Physical testing emphasized wet strength retention and tear strength measurements. A nitrile silicone fluid as primer exhibited exceptional wet strength retention. Precision slitting experience was gained. Final tape samples, the first requiring semicontinuous processing equipment, were supplied. A glassreinforced magnetic tape base with advantages warranting continued development was achieved. Author
