Improving 8mm — Type S (Super-8) Optical Sound by Design of Film and Recording System

The factors are examined that need to be improved in order to achieve a substantial improvement in the quality of 8mm – Type S (super-8) sound using the variable-area optical sound approach. As a result of the study, Fuji Fine Grain Sound Recording Film (Variable Area) Type II was developed and is being sold on a trial basis. Being of superfine grain and ultrahigh resolution, this film is intended for sound recording use exclusively with the 8mm – Type S system; its panchromatic emulsion resembles that of high-resolution microfilm, and its speed is comparable to that of Fuji Type 72412 film. Actually realizing the benefits of using such a film, however, requires that a high-performance nonslip printer such as the Peterson printer be used in the printing stage. The use of Fuji Type II film and such a printer permits a 10-dB improvement in output at 5 kHz over other conventional systems.
