Abstract
Embodiments of the present invention generally relate to a HAMR device having two temperature sensors. The first temperature sensor is disposed adjacent a waveguide and is about two or more micrometers away from an air bearing surface. The first temperature sensor has a length, a width and a thickness, and the length is greater than the width and the thickness. The length of the first temperature sensor is substantially perpendicular to the waveguide.
