High-Speed Magnetic Sound Transfer to 8mm Films

A technology has been developed for transfer of magnetic sound at 150 ft/-min, making possible the production of 8mm sound prints economically on prestriped print film. An experimental printer, which can accommodate any current or proposed 8mm format with magnetic sound, has been designed and built to operate at 7.5 X projection speed. This inertia-controlled printer will print, in one pass, from a 16mm magnetic sound master two separate records simultaneously onto a double super 8 film at 150 ft/min. Amplifiers and compensating circuits have been constructed which make possible re-recording of magnetic records at this high speed.
