Abstract
The fringe field for magnetic recording heads of finite pole-tip length containing a current conductor in the pole-tip region of the gap is obtained using conformal mapping techniques. Isolated readback pulse data as a function of pole-tip length and related geometrical parameters are tabulated for typical parameter values of interest. "All ones" output voltage versus transition density is computed for pole-tip length equal to gap length and for infinite pole-tip length.
