Abstract:
The present disclosure relates to heat-assisted magnetic recording (HAMR) write heads including a waveguide and a main pole having a main pole tip. One or more current paths are provided through the main pole tip. Terminals of the one or more current paths can be coupled to the main pole, a trailing shield, a leading shield, a heat sink layer, a touch pad, a pole diffusion barrier layer, a NTS sensor, or another suitable component of the HAMR write head.
