Magnetic Design Theory for Tape Recorder Heads

Authors: McKnight, John G.

Journal of the Audio Engineering Society · Volume 27 · Issue 3 · pp. 106–120 · March 1979

Abstract

The circuit models, formulas, and a computer program in BASIC language are given for calculating the efficiency, frequency response, and complex impedance of a magnetic recording or reproducing head. The model and the calculations take into account the effects of the complex permeability of the elements: a core of nonhomogeneous laminations of specified thickness and geometry; a front gap with nonconducting or conducting gap spacer; gap stray permeance; and a read gap. Measurements presented on eight different heads prove the model and the calculations.
