Abstract
A heat-assisted magnetic write head includes: a magnetic pole having an end surface exposed to an air bearing surface; a waveguide extending toward the air bearing surface to propagate light; 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; and a clad provided to surround both the waveguide and the plasmon generator collectively, the clad having a refractive index lower than that of the waveguide, and exhibiting a thermal conductivity higher than that of the waveguide. The clad may be provided to collectively surround the magnetic pole, as well.
