Paper Abstract

The FOSDIC System requires that machine tabulation cards be copied onto 16mm film, the records from 13,000 cards occupying one 100 ft. reel. The exposed film is processed and printed in a "clean room area". The largest permissable size for foreign particles is 10 microns. Information retrieval, or printing from the film records back to cards, employs techniques using a flying spot scanner. Hence the need for elimination of larger size foreign particles. Specific cards may be recreated on demand.
