Laserfilm

Developed by McDonnell-Douglas in 1984, the laser filmisa transmissive laser based playbackmedium. Working on the topology that laser has to shine through one side of the disc to a receiving sensor on the other side, where the beam of the laser would be interrupted by a spiral of small dots on the disc,which can then modulate the laser beam to represent the video and audio information, which was then interpreted by the receiving sensor receiving the beam on the other side Made of the ordinary photographic film, similar to the Selectavision CED videodisc system, this wasn’t successfully marketed by McDonnell-Douglas, thesole manufacturer of the laser film player. Having originated from ARDEV, which was originally a subsidiary of Atlantic Richfield until 1981, this format is usually employed in flight stimulators.
