photoscopic1955

1955 Sci. Amer. June 100/3 Gilbert W. King..has undertaken to exploit the great density of information storage that is possible through the use of high-resolution photographic emulsions. With his ‘photoscopic’ technique information can be stored at densities more than a hundred times as great as those possible in magnetic media.

1963 Amer. Anthropologist 65 756 Storage capacity of high speed permanent memory is soon to be so great, due to engineering developments such as the photoscopic disc, that [etc.].

1970 O. Dopping Computers & Data Processing x. 151 One example of photographic film memories is the photoscopic memory, which has been used for dictionaries in mechanical translation from one natural language to another. The medium is a continuously rotating disk of transparent plastic carrying a photographic layer upon which a pattern corresponding to zeroes and ones has been recorded.
