Developments in Magnetic Striping 8mm Sound Film
Although the idea of coating a stripe of magnetic material on the edge of motion-picture film was the subject of American patents as early as 1919, it was not commercially feasible for 8mm film until recently. Successful 8mm sound projectors became possible after the development of high-precision, long-wearing magnetic heads and low-cost compact electronic components. Two machines for coating magnetic stripes on film have been produced by Soundcraft, the first for coating 16mm raw stock, and the second for coating 8mm processed film.
