Abstract
A write head design with pedestal-defined throat and flat-top pole is presented. The flat-top pole design enables critical dimension control and extendibility to narrower feature size. Write head performance improves further by implementing a single-layer six-turn, closely packed coil with yoke length of 14 (mu)m and incorporating a sputtered high moment material on both top and bottom poles. With write current of 40 mA, better than 35 dB overwrite and less than 16% (-16dB) nonlinear transition shift can be achieved on the medium with coercivity of 4400 Oe and Mrt of 0.32 memu/cm/sup 2/ at areal densities up to 60 Gb/in/sup 2/.
