Optimum High-Frequency Bias in Magnetic Recording

G. L. Dimmick, S. W. Johnson

An experimental study was made of magnetic tapes and films produced by several manufacturers. The effects of bias current upon the frequency characteristic, the reproducing level, and the harmonic distortion are shown. Conclusions are drawn as to the best method of testing a given tape for the optimum value of high-frequency bias.
