Abstract
The present disclosure is generally related to a magnetic recording device comprising a magnetic recording head having a current flow in a cross-track direction around a 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 main pole and the trailing shield. A hot seed layer is disposed between the trailing gap and the trailing shield. A first insulation layer is disposed between the hot seed layer and the trailing shield, where the first insulation layer contacts the side shields. A second insulation layer is disposed between the main pole and leading shield, where the second insulation layer contacts the side shields. The first and second insulation layers direct the current through the side shields and across the main pole in a cross-track direction.
