20160019918 | SUSPENSION ASSEMBLY AND DISK DRIVE WITH THE SAME - According to one embodiment, a suspension assembly includes a base plate having a securing plate portion protruding outwardly from a side edge of the base plate, a load beam secured on a first surface of the base plate and extending from the base plate, and a wiring member. The wiring member includes a distal side portion attached to the load beam and the first surface of the base plate, and a proximal side portion extending outwardly from the side edge of the base plate and extending in a direction opposite to the load beam along the support surface. | 01-21-2016 |
20160078886 | HALF-FINISHED HEAD SUSPENSION - A positioning method positions a flexure whose front end side is joined to an outside frame with respect to a load beam, keeps the positioned state of the flexure and load beam, plastically deforms the outside frame to bead the front end side of the flexure so that the position of a tongue of the flexure is adjusted to the position of a dimple of the load beam, and joins the flexure and load beam to each other to keep the position adjusted state of the tongue. | 03-17-2016 |
