Equipment and Film Parameters for Optimum Magnetic Sound Transfer on Super-8 Print Film
In the motion-picture industry difficulty has been encountered in transferring magnetic sound to super-8 prestriped film. Either of two film “configurations” has been used. The first, or “A,” configuration is a direct carryover from the tape industry. The second, or “C,” configuration was used in the high-speed magnetic sound printer described in 1966.2 A similar technique is used on some magnetic sound projectors. Because of the difficulties encountered, a comprehensive study was undertaken to analyze the effects of the various operational parameters of both methods of recording. Studied were: (1) physical film condition, (2) film path configuration, (3) head pressure, (4) head design and (5) film guiding. It was conclusively demonstrated that the film path configuration is of primary consideration. The “C” or “on-the-drum” recordings provide the best assurance of quality sound transfer whether to raw or processed film. With this configuration the importance of the other variables is reduced.
