A head suspension assembly comprising: a head suspension; a head slider having the medium-opposed surface opposed to a storage medium, the head slider having the supported surface received on the head suspension, the supported surface being defined at the farside of the medium-opposed surface; an electromagnetic transducer embedded in the medium-opposed surface of the head slider; a light waveguide incorporated in the head slider, the light waveguide extending from the supported surface to the medium-opposed surface; and an optical element interposed between the supported surface and the head suspension, wherein the optical element defines: a light-collecting surface configured to collect light input into the optical element in parallel with the supported surface; and a light-reflective surface configured to reflect the light at a predetermined angle so as to direct the light to the light waveguide.
