Current perpendicular-to-plane-giant magnetoresistance (CPP-GMR) read heads with 80 nm sensor width and wraparound shielded write heads with 150 nm pole width are fabricated and tested. A perpendicular medium of 6.2 kOe coercivity and 520 emu/cm/sup 3/ is used for read-write testing. Both wraparound...
