Definitions[edit | edit source]
Computer-Output-on-microfilm (COM) (also computer output microfilm) is
|“||a process for copying data from storage media on a computer onto microfilm. COM can be produced as microfiche or as 16mm-roll microfilm.||”|
|“||a technology enabling the output of computers be recorded directly on microfilm rather than on paper. It is a blending of the computer, microphotography, and electronics. This process is faster than printing on paper, and the information produced is more accessible and occupies less space than paper reports.||”|
|“||[m]icrofilm that contains data that are received directly from computer-generated signals.||”|
Overview[edit | edit source]
A COM system usually consists of a recorder/developer and a reader. The recorder/developer equipment may be in a single unit or each unit may be separate. The recorder reads computer magnetic tape, reduces the physical size of the data, and transforms it onto film, which is then developed. The reader, the main vehicle for retrieving information on microfilm, magnifies the reduced data on the film so a report user can read it.
