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 HAMR transducer includes a write pole, a waveguide, and at least one protective pad. The write pole has a pole tip with an ABS facing surface. The waveguide is located in a down track direction from the pole tip and directs light from the laser toward the ABS. The protective pad(s) are adjacent to the write pole and have front surface(s) at the ABS.
