Magnetic Recording Tape: The Influence of the Magnetic Coating Thickness Upon Signal Parameters

Authors: Manly, Jr., William A.

AES Convention 35 · Paper 614 · October 1968

Abstract

An empirical study has been made on the dependence of bias, sensitivity, response, output at saturation, distortion, print through, and noise, on the thickness of the magnetic coating. It is shown that for audio and instrumentation (analog) tapes, where the record head gap is sufficiently long, the greatest percentage of the variations observed in measured parameters is due to the variation in the thickness of the magnetic coatings. In some cases, the customer requirements are such that specification limits require resolutions in coating thickness measurements which are almost unobtainable.
