Abstract :
An analysis is made of the recording fields for heads whose permeability is a nonlinear function of flux density. Poisson´s and Laplace´s equations of a vector magnetic potential are solved by a successive overrelaxation method. The magnetic saturation of the head core at a large field and the effect of permeability at a small field are analyzed.
