Abstract
A heat-assisted magnetic write head includes a magnetic pole having an end surface exposed at an air bearing surface, a waveguide extending toward the air bearing surface to propagate light, and a plasmon generator provided between the magnetic pole and the waveguide, and generating near-field light from the air bearing surface, based on the light propagated through the waveguide. The plasmon generator has an end portion exposed at the air bearing surface or located in close proximity to the air bearing surface, the end portion having a minimum thickness in a region close to the waveguide.
