Abstract
A write head including a bearing surface and a write pole having a front surface that forms a portion of the bearing surface. The front surface has a leading edge, a trailing edge and side edges connecting the leading and trailing edges. The write head also includes side shields proximate to the side edges of the write pole, and a trailing shield over the write pole and the side shields. A trailing shield-write pole gap is present between the trailing edge and the trailing shield, and a trailing shield-side shield gap is present between the trailing shield and the side shields. The trailing shield side shield gap is substantially less than the trailing shield-write pole gap.
