Abstract
The fringing field and inductance of a typical video head are calculated numerically for geometries and permeabilities where the conventional approximations fail. The head material is assumed to be nonconductive and of constant isotropic permeability. The calculations, having no arbitrary factors, yield absolute results. Certain consequences of these findings on the write and reproduce processes are outlined.
