Laserfilm was a videodisc format developed by
McDonnell-Douglasin 1984that was a transmissive laser-based playback medium (unlike its competitor, laserdisc, which was a reflectivesystem). It worked by having the laser 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. This would in turn 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.
The disc was made out of ordinary
photographic film(hence the format's name), which was mounted in a caddy for playback, much like the RCA SelectavisionCED and VHD videodisc systems.
Laserfilm players were chiefly manufactured by McDonnell-Douglas, and weren't marketed successfully outside of the company. However, the format was employed for use in their
flight simulators, by linking several players together.
The Laserfilm format was originally based on an earlier videodisc format called ARDEV, developed by a company of the same name which was originally a subsidiary of
Atlantic Richfielduntil 1981. At that time, ARDEV and all of its videodisc technologies were acquired by McDonnell-Douglas.
