A perpendicular magnetic recording writer is disclosed with a side shield separated from a write pole side by a gap layer at an air bearing surface (ABS) where the side shield has a first sidewall facing the write pole with an end at height (h1) from the ABS, and a second sidewall at height h1 that is parallel to the ABS. The write pole side is curved such that a first portion proximate to the ABS is at an angle of 0 to 40 degrees with respect to a center plane formed orthogonal to the ABS, and a second section proximate to a corner where the curved side connects with a flared main pole side is formed substantially parallel to the second sidewall. When h1 is 30-80 nm, and the corner is 80-150 nm from the ABS, overwrite is improved while cross-track field gradient is enhanced.
