Abstract

See full text

The present disclosure is generally related to a magnetic recording device comprising a magnetic recording head having a first current flow in a cross-track direction through a trailing shield. In one or more embodiments, a second current flows in a cross-track direction around the main pole. The magnetic recording device comprises a main pole disposed between a trailing shield, a leading shield, and side shields. A trailing gap is disposed between the side shields and the trailing shield. A high moment seed layer is disposed between the main pole and the trailing shield. A first insulation layer is disposed within the trailing shield and directs the first current through the trailing shield, guided to the proximity of the main pole. A second insulation layer, disposed below the trailing shield, directs the second current through the trailing shield, or alternatively through the side shields and around the main pole.
