摘要： A laser diode is fixed to a light source support substrate and a first surface of a slider substrate is fixed to a second surface of the light source support substrate; therefore, the slider substrate and the laser diode are kept in a fixed positional relation. Since the laser diode faces a light entrance face of a core, long-distance propagation of light as in the conventional technology does not occur, and light emitted from a light emitting element is guided well to a medium-facing surface while permitting some mounting error and coupling loss of light. A spot size w of a light intensity distribution along the X-axis in the XY plane including an incident-light centroid position on the light entrance face is set larger than a thickness of the core, whereby variation in incidence efficiency is well suppressed against positional deviation.

摘要： A slider has a slider substrate, an electromagnetic transducer, a waveguide for receiving light from a surface on the side opposite from a medium-opposing surface and guiding the light to the medium-opposing surface side, and a device electrode electrically connected to the electromagnetic transducer. A light source unit includes a light source supporting substrate, a light source, and a lead extending from the slider side to the side opposite from the slider and having both end parts exposed at a surface of the light source unit. 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. An end part on the slider side of the lead of the light source unit is soldered to the device electrode of the slider.
