Patent ID: 8374061

Claim:
A thermally assisted magnetic head comprising a slider having a medium-opposing surface, and a light source unit arranged on a surface of the slider on the side opposite from the medium-opposing surface; wherein the slider has a slider substrate, an electromagnetic transducer, a waveguide for receiving light from the surface opposite from the medium-opposing surface and guiding the light to the medium-opposing surface side, and a device electrode electrically connected to the electromagnetic transducer; wherein the light source unit has a light source supporting substrate secured with respect to the slider substrate, a light source secured with respect to the light source supporting substrate so as to be able to supply the light to the waveguide, and a lead extending from a slider-opposing side of the light source unit to a side opposite from the slider-opposing side and having both end parts exposed at a surface of the light source unit; wherein the device electrode of the slider is exposed at the surface of the slider on the side opposite from the medium-opposing surface without being covered with the light source unit, or exposed at a side face of the medium-opposing surface of the slider; and wherein an end part of the lead on the slider-opposing side of the light source unit is soldered to the device electrode of the slider.
