[SCM] Potterfringeheadmodel DL : 0: Implementation of the Potter head field equations. (C) 2000, C. Bond. All rights reserved. "Analytic Expression for the Fringe Field of Finite Pole-Tip Length Recording Heads", Robert I. Potter, IEEE Trans. on Mag., Vol. MAG-11, pp. 80-81, January 1975. The above cited paper presented an expression for calculating the Hx field value for a thin film head. Potter s results were used by Szczech in a comparison with his own method (1979). Some limitations on the method are: 1) Use of Karlquist field for central pulse, 2) Assumption of equal pole thicknesses, 3) No equation for Hy field. Because of limitation 2), the calling conventions for this routine do not require a head geometry structure. All relevant quantities are passed directly as function parameters, and the (normalized) Hx field value is the returned result. -Implementation of the Potter head field equations. (C) 2000, C. Bond.
