Abstract: Magnetic sound recording on 8mm film demands close tolerances on both stripe dimensions and magnetic-audio performance because the system requires a narrow stripe and a low film speed. The requirements of good design of a striping machine are reviewed with particular attention to positive film positioning and stripe placement at the striping point, constant speed film drive and minimum film tensions. A coating head and a corresponding high-viscosity magnetic dispersion are described that together define stripe width, thickness and contour. This system has been used by the Eastman Kodak Co. to provide 8mm Sonotrack coatings since May, 1960; the quality control data from this operating experience indicate good production control. Operating techniques are presented for the guidance of processing laboratories who may wish to design similar striping systems.
