Abstract
Provided is a structure of a heat assisted magnetic recording head gimbal assembly that allows common inexpensive TE-mode LDs to be utilized. The heat assisted magnetic recording head gimbal assembly comprises: a light source unit having a light emitting element mounted on a parabolic solid submount; a heat assisted magnetic recording head comprising a magnetic recording element, a read element, a near field transducer, and a waveguide for guiding light from the light emitting element into the near field transducer; a slider including the heat assisted magnetic recording head and which flies above a disk; and a suspension for supporting the slider. The light emitting element of the light source unit is an edge-emitting LD and the light source unit is arranged on the opposite side of an bearing surface of the slider such that the light emitting surface of the light emitting element faces the slider, apertures are created in the suspension, and the slider is connected to the suspension in a way that a part of the light source unit penetrates through the apertures of the suspension.
