摘要
A magnetic write apparatus has a media-facing surface (MFS), a pole, a write gap, a top shield and coil(s). The pole includes a yoke and a pole tip. The pole tip includes a bottom, a top wider than the bottom and first and second sides. The pole tip has a height between the top and the bottom. At least part of the top of the pole tip is convex in a cross-track direction between the first and second sides such that the height at the MFS is larger between the first and second sides than at the first and second sides. The height increases in a yoke direction perpendicular to the MFS. The write gap is adjacent to and conformal with the top of the pole at the MFS and is between part of the top shield and the pole. The top shield is concave at the MFS.
