Computer-Output-Microfilm (COM) Activities and Experiences at the Defense Documentation Center

摘要

Since Novenber 1969 the Defense Documentation Center (DDC) has been experimenting with Computer-Output-Microfilm (COM) equipment and techniques. Stromberg-Datagraphix equipment was selected primarily for two reasons: the reputation and practical experience of this manufacturer and the capability of producing roll film or microfiche with a single unit. The findings indicate there are significant benefits to DDC from using COM equipment. Depending upon the type of application, the cost savings could be as high as 87%. COM also provides greater flexibility in the format of the output product. Reports could be in roll film, fiche, or hard copy produced from COM film. The size of the hard copy can be varied to accommodate differing needs and preferences. Greater speed and reduced storage requirements make it practical to produce reference products which could not previously be considered. For example, complete sets, on 16mm film, of Technical Abstract Bulletin entries in numeric order by AD number, and indexes to them, for the ten-year period 1960-1969. From a systems standpoint there are a number of uses for COM equipment: as a stand alone printer; in conjunction with other film handling equipment; and to produce film for a remote inquiry information retrieval system.
