Abstract: A magnetic recording head includes a write pole including an end proximal to a media-facing surface of the magnetic recording head, a return pole disposed a distance from the write pole in a down-track dimension of the magnetic recording head, and a writer coil configured to produce a magnetic flux in the write pole. The writer coil includes a first segment and a second segment. The first segment is disposed proximal to the end of the write pole and between the write pole and the return pole. The second segment is electrically coupled to the first segment. A thickness of the second segment in the down-track dimension is greater than a thickness of the first segment in the down-track dimension.
