Abstract: A heat assisted magnetic recording head gimbal assembly comprises a light source unit, a heat assisted magnetic recording head, a suspension, an actuator, and a slider. The light source unit comprises a light emitting element and a submount. The suspension comprises a load beam and a flexure movably coupled with the load beam. The actuator is deformably coupled to the flexure. The slider is supported by the suspension and coupled to the flexure and the light source unit. The slider includes the heat assisted magnetic recording head. First and second solders or conductive adhesives are positioned on opposite longitudinal sides of the light source unit, so that the first solder or conductive adhesive electrically and mechanically connects the submount to a wiring supplying power, while the second solder or conductive adhesive electrically and mechanically connects the light emitting element to the wiring.

Abstract: A magnetic storage device comprising a magnetic disk and a carriage arm rotatably movable relative to the magnetic disk. A suspension assembly of the magnetic storage device is coupled to the carriage arm and comprising a flexure. The magnetic storage device additionally comprises a slider comprising a read-write head. The flexure comprises a fixed portion co-movably fixed relative to the carriage arm and a hinge portion to which the slider is co-movably fixed. The hinge portion is swayable relative to the fixed portion. An actuator system of the magnetic storage device is coupled to the fixed portion of the flexure and the hinge portion of the flexure. The actuator system is operable to sway the hinge portion relative to the fixed portion. The magnetic storage device includes a repolarization enhancing feature adjacent the actuator system.

Abstract: Described herein is a connector assembly that comprises a head-gimbal assembly (HGA) tail connector, a flex connector, and an adhesive. The HGA tail connector comprises a pad support, an HGA pad coupled to the pad support, and an HGA trace coupled to the pad support and electrically coupled to the HGA pad. The flex connector comprises a substrate, comprising a first side and a second side, where the first side is opposite the second side. The flex connector also comprises a flex pad coupled to the first side of the substrate, a flex trace coupled to the second side of the substrate, and a via extending through the substrate from the first side to the second side. The via electrically couples the flex pad and the flex trace. Also, the adhesive adheres the HGA pad of the HGA connector in electrical contact with the flex pad of the flex connector.
