Abstract
A method fabricates a heat assisted magnetic recording (HAMR) transducer having an air-bearing surface (ABS) and that is optically coupled with a laser. The method includes providing a waveguide for directing light from the laser toward the ABS and providing a write pole having a pole tip with an ABS location facing the surface. The pole tip is in a down track direction from the waveguide. The method also includes providing at least one shield including a shield pedestal. The shield pedestal is in the down track direction from the pole tip. At least one protective pad is provided adjacent to the write pole and between the ABS location and the shield pedestal.
