Film Discs Replace Ribbon Film (Dec, 1932)
Film Discs Replace Ribbon Film
FILM discs replace ribbon film in a new type movie machine recently introduced. The device projects pictures from a film disc that greatly resembles a phonograph record. The disc measures 18 in. in diameter, which equals 1,000 feet of ordinary movie film. A unique optical arrangement allows the pictures to be transposed from standard sized motion picture films to be printed spirally on the disc.
Although each individual picture is only 3/8″x9/32″ in size there is no loss of definition or smoothness on the screen. The great advantage in this new type movie machine is that the disc’s film can be used over and over again for at least 10,000 projections as compared to the usual 200 projections which is the life of the conventional type film.
The machine is designed for use in schools and for advertising and industrial use where the disc’s long life is a great advantage.
