Abstract :
Design improvements of the metal-in-gap head for rigid disk files, using a finite-element method that takes into account magnetic saturation, are discussed. The saturation flux density and the thickness of the alloy film and the throat height of the head are discussed analytically in order to obtain a more intensive and sharper field. The proposed analytical design is confirmed by measurements using an improved scanning electron microscope. The calculated and measured field results are in close agreement
