Claim:
1. A perpendicular magnetic recording (PMR) writer, comprising: (a) a main pole with a leading edge at an air bearing surface (ABS), and a trailing edge at the ABS and formed at a first plane that is orthogonal to the ABS and to a center plane formed equidistant between two main pole sides that connect the leading edge and the trailing edge; (b) a gap layer surrounding the main pole at the ABS and comprising a write gap that contacts the trailing edge and has a first cross-track width between a first side and a second side at the first plane, a side gap layer adjoining each of the main pole sides, and a lead gap contacting the leading edge at a second plane that is parallel to the first plane; and (c) a hybrid side shield (hSS), comprising;
