摘要：
A heat-assisted magnetic recording head includes a magnetic pole, a waveguide that allows light to propagate therethrough, a near-field light generating element that generates near-field light based on the light propagating through the waveguide, a convergent lens, and a laser diode disposed above the waveguide. The convergent lens transmits light that is emitted from the laser diode, so that the light transmitted through the convergent lens is incident on the waveguide.
