Abstract:
1. A head gimbal assembly comprising: a suspension; and a heat-assisted magnetic recording head attached to said suspension and comprising a slider and a light source unit joined to said slider, said light source unit comprising: a unit substrate; and a light source provided on a source-installation surface of said unit substrate, said slider comprising: a slider substrate; and a head part formed on an element-integration surface perpendicular to an opposed-to-medium surface of said slider substrate, said head part comprising a write head element for writing data to a magnetic recording medium, a waveguide for guiding light being incident on an end opposite to the opposed-to-medium surface toward the opposed-to-medium surface, and at least one electrode, an end surface opposite to the opposed-to-medium surface of said slider substrate being bonded to said suspension, said suspension comprising an opening, and said light source unit projecting through said opening to an opposite side to said slider in relation to said suspension, a first pad being provided on an upper surface of said suspension, and a second pad provided on a lower surface of said suspension, and an end surface opposite to the source-installation surface of said light source being connected to said first pad by a first connection member, and said at least one electrode of said head part being connected to said second pad by a second connection member.
