1. The computer displays the results onto the screen.
2. The contents are then photographed onto the microform (an online operation).
Alternatively, the computer can write the output into a storage medium, e.g. Magnetic tape.
3. The data on the tape is then read by transcriber machine called the Microform recorder & displays them on a screen connected to the machine.
4. The contents being displayed on the screen are then photographed by a high-speed camera using microfilm onto the microform.
Since the transcriber machine is not under direct influence of the computer, the operation is Off-line.
5. The film is then developed.
6. If necessary, duplicates are made using the Film duplicator.
In some systems, a separate device is needed for each of these stages. In others, the tape drive is not needed, instead the computer sends the output directly to the Microfilm recorder.
Also, some recorders are capable of processing the film, so a separate film developer is not needed.
In order to view a film, a Microfilm viewing station is used. This magnifies the images on the film so they can be easily read.
The station usually has a Printer connected to it to produce hardcopy, if required.
