Abstract
The present invention generally relates to electrically connecting a laser diode to a slider and head assembly of a TAR head in a HDD. The laser diode is coupled to a sub-mount. The laser diode and the sub-mount are coupled to the top surface of the slider and/or the head assembly. Either the slider, the head assembly or both have bond pads exposed through their respective top surfaces to provide an electrical connection to both the laser diode and the sub-mount. Both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads and are in contact with the bond pads. Conductive bonding material is used to not only bond the laser diode and the sub-mount to the bond pads, but also to electrically connect the bond pads to the electrodes.
