Patent ID: 8179635

Claim:
A thin film perpendicular head comprising; a write pole having an upper surface, a lower surface opposing said upper surface, a first side surface, and a second side surface; a first non-magnetic side gap in contact with said first side surface of said write pole; a second non-magnetic side gap in contact with said second side surface of said write pole; a wrap around shield situated above said write pole, said wrap around shield in contact with said first and second non-magnetic side gaps; a non-magnetic top gap in contact with said upper surface of said write pole, said non-magnetic top gap situated between said wrap around shield and said write pole; a non-magnetic bottom gap in contact with said lower surface of said write pole, said non-magnetic top gap having a thickness approximately equal to a thickness of said non-magnetic bottom gap; and, an auxiliary pole, having a top surface, said bottom gap in contact with said top surface of said auxiliary pole.
