Patent ID: 8854932

Claim:
A head-gimbal-assembly comprising: a thermal assisted magnetic recording head including: a sub-mount having a sub-mount electrode for power supply to a laser diode; the laser diode attached to an attachment face of the sub-mount, provided with a laser diode electrode on the other end face side of the attachment face; and a head slider having: a magnetic write head; a near field transducer for converting laser light emanated from the laser diode into near field light; and a head slider electrode, the head slider outputting the near field light from a plane opposed to recording media; a gimbal supporting the thermal assisted magnetic recording head; and a plurality of lead wires formed over the gimbal, the lead wires each being branched off to the right and left sides of the head slider, on the gas inlet side thereof to advance toward the gas-outlet side of the head slider after taking a detour around the head slider to be subsequently connected to the head slider electrode, the sub-mount electrode and the laser diode electrode, wherein the sub-mount with the laser diode attached thereto is mounted on either the right or the left side lateral face of the head slider, wherein the head slider receives the laser light of the laser diode from the lateral face of the head slider, with the sub-mount mounted thereon, and wherein two lengths of the lead wires, each length thereof being connected to the sub-mount electrode and the laser diode electrode, respectively, are each branched off to the right and left sides of the head slider, on the gas inlet side thereof to advance toward the gas-outlet side of the head slider after taking a detour around the head slider, whereupon one length of the lead wire circles around the outer periphery of the head-slider electrode formed on the gas-outlet side of the head slider to be connected to the sub-mount electrode or the laser diode electrode, while the other length of the lead wire is connected to either the sub-mount electrode or the laser diode electrode, differing from either of those electrodes where the one length of the lead wire is connected, without circling around the outer periphery of the head-slider electrode formed on the gas-outlet side of the head slider.
