Abstract
The Material Laboratory has developed a method for measuring the magnetic strength existing on 16mm magnetic soundtrack by utilizing a nonmagnetic loop for the determination of the absolute surface induction at 400 cycles/sec for “pegging” the relative surface-induction vs. frequency characteristic obtained by the “short” gap or other approved method. This paper indicates that this method was found to be practical for determining the surface induction for signals recorded on the currently manufactured 16mm magnetic-coated film, independent of differences in their characteristics and the depth of penetration of the recorded signal.
