  • Patent number: 7380329
    Abstract: A method of assembling a head gimbal assembly. The method comprises a series of steps which include: stacking a base plate, a load beam, and a flexure to form a three-layered stacked series with at least a bottom layer being a base plate series; joining portions of the load beam to the base plate, and the flexure to the load beam in the three-layered stacked series to make a suspension section; attaching a slider to the flexure in the suspension section to make a head gimbal assembly; load-bending a hinge portion formed in the head gimbal assembly; and heating the hinge portion in order to adjust a bending load on the hinge portion at a predetermined bending angle to a predetermined value.

  • Patent number: 7210221
    Abstract: A base plate and load beam for an HG assembly are formed in series, stacked, and transferred by a transfer system in the form of the stacked-layer series to undergo the necessary assembly processes such as layer joining, slider attachment, and electrical connections between the terminals thereon. When uncompleted HG assemblies are transferred for each of the manufacturing processes, the uncompleted HG assembly is mounted on the assembly jig such as a tray or a block for transference. For this reason, assembling jigs, the number of which is at least equal to the number of the uncompleted HG assemblies remaining at the respective assembly processes would be needed. Accordingly, the efficiency of work space is reduced, and a rise in manufacturing cost is brought about by the need for the assembling jigs.

  • Patent number: 7161766
    Abstract: A base plate and load beam for an HG assembly are formed in series, stacked, and transferred by a transfer system in the form of the stacked-layer series to undergo the necessary assembly processes such as layer joining, slider attachment, and electrical connections between the terminals thereon. The base plate structure comprises a band portion having conveying holes and positioning holes formed at a predetermined pith respectively in a longitudinal direction. A plurality of the base plates are disposed via connecting portions integrally formed at a predetermined pitch at edges on one side of the band portion.
