Abstract
The thermally-assisted magnetic recording head includes: a magnetic pole; a waveguide allowing a transverse-electric (TE) wave oscillating in a cross-track direction to propagate toward an air bearing surface; and a plasmon generator having a tip portion near the air bearing surface, the tip portion being provided to overlap, in a down-track direction, with both the magnetic pole and the waveguide, and having a quadrangular cross-section substantially parallel to the air bearing surface.
