Abstract
A magnetic write head for perpendicular magnetic data recording. The write head includes an wrap around trailing shield structure for improved write field strength, reduced skew related adjacent track interference and magnetic core width. The trailing wrap around shield includes a side shield that is separated from sides of the write pole by a side gap that is narrower near the leading edge of the write pole and wider near the trailing edge of the write pole.
