Convention Paper

The Use of 35-mm Sprocket Type Magnetic Film in Recording Phonograph Masters

Authors: Frayne, John G.; Stafford, J. W.

AES Convention 11 · Paper 114 · October 1959

Abstract

Although not in general use in the disk recording industry, 35-mm perforated magnetic film offers many advantages as the transfer medium from original audio signals to the final master disk recording. Its flutter, signal-to-noise ratio, modulation noise (noise behind the signal), print-through and intermodulation characteristics are excellent and, as demonstrated by its use in the motion picture industry, ease of handling and particularly editing makes it a useful recording medium. Data comparing performance characteristics to 1/4 inch tape recording will be given. Finally, as an example of 35-mm perforated magnetic film as the transfer medium in the preparation of stereo disk masters, the system used by Mr. Harry Belock at the Belock Recording Studios will be described.
