Abstract :
A transmission-line model for thin-film heads is presented in which the magnetic structure is divided into four sections. In one of them, the width decreases at a constant rate; in another, the spacing between the magnetic layers behaves in a similar way. The appropriate differential equations are solved and the boundary conditions are satisfied. Frequency effects are incorporated by way of complex effective permeabilities. Edge effects are taken into account. The computed impedance functions agree well with experiment
