definition
Analogous to the sound tape cassette. Consists of a strip of photographic film wound onto a double core, housed in a protective container. Microfilm cassettes require reading equipment (readers and reader-printers) that is specifically adapted for their use. Because they are double-cored, they are not threaded when used in such readers and reader-printers. Usual film lengths are 100 ft (approximately 30 m.) or less. Common film width is 16 mm. and usual reduction ratios are those of microfilm reels and cartridges.
