Abstract:
1. A heat assisted magnetic recording head gimbal assembly comprising: a light source unit mounting a light emitting element to a rectangular solid submount; a heat assisted magnetic recording head comprising a magnetic record element, a read element, a near field transducer, and a waveguide guiding the light from the light emitting element to said near field transducer; a slider including the heat assisted magnetic recording head, and configured to fly above disk; and a suspension supporting the slider; wherein the light emitting element of the light source unit is an edge-emitting LD of TE mode, and the light source unit is arranged in a way that the light source unit is on the opposite side to an air bearing surface, and the emitting surface of the light emitting element is opposite to the slider; wherein the suspension is formed with apertures; and wherein the slider is jointed to the suspension in a way that a part of the light source unit penetrates through the apertures of the suspension: wherein a wiring is formed on a joint of the suspension to the slider for supplying power; wirings are formed on the joint part of the light emitting element to the submount and on the opposite side to the joint part respectively; a metal film is formed on the joint surface of the submount to the light emitting element; the wiring formed on the joint part of the light emitting element to the submount is connected to the metal film formed on the joint surface of the submount; a metal film is exposed at the end of the one side of the wiring in the neighborhood of the light source unit in the direction of the opposite side to the joint surface to the slider; and the wiring formed on the opposite side to the joint part of the light emitting element to the submount and the metal film formed on the submount are electrically connected to the end of the metal film of the wiring.
