ABSTRACT:
Disk drive systems and associated methods of fabrication are disclosed for a write head having an integrated coil and shield structure. The write head includes a write pole having a pole tip adjacent to an air bearing surface, and a return pole having a surface adjacent to the air bearing surface. The write pole and the return pole are connected to one another by a back gap section that is distal from the air bearing surface. The write head also includes a coil formed from electrically conductive materials. The coil includes a segment that is formed proximate to the air bearing surface. The coil segment is formed from a ferromagnetic material so that the coil segment acts as a shield for the write pole.
