What is "auricon"

Auricon cameras were 16 mm film Single System sound-on-film motion picture cameras manufactured in the 1940s through the early 1980s. Auricon cameras are notable because they record sound directly onto an optical or magnetic track on the same film as the image is photographed on, thus eliminating the need for a separate audio recorder. The camera preceded ENG video cameras as the main AV tool of television news gathering due to its portability - and relatively quick production turn-around - where processed negative film could be broadcast by electronically creating the positive image. Additionally, the Auricon found studio use as a ' kinescope' camera of live video off of a TV screen.
