  • Load beam spring portion with enhanced resistance to plastic deformation in manufacturing processes
    Patent number: 7265944
    Abstract: A load beam for a disk drive suspension in which the radius of the perimeter transition between the load beam portion and the load beam spring portion is increased to ensure the stress encountered when the load beam is bent from its normal range, for installation into a disk drive, for example, from a previously typical 0.002 inch to 0.010 inch, is distributed sufficiently that the load beam spring portion is subject to only elastic, not plastic deformation. Thus, the gram loads exerted by the load beam spring portion are reliably consistent.
    Type: Grant

    Date of Patent: September 4, 2007
    Assignee: Magnecomp Corporation

  • Load beam with enhanced resistance to plastic deformation in manufacturing processes
    Patent number: 6833977
    Abstract: A unitary load beam for a disk drive suspension in which the radius of the perimeter transition between the load beam portion and the load beam spring portion is increased to ensure the stress encountered when the load beam is bent from its normal range, for installation into a disk drive, for example, from a previously typical 0.002 inch to 0.010 inch, is distributed sufficiently that the load beam spring portion is subject to only elastic, not plastic deformation. Thus, the gram loads exerted by the load beam spring portion are reliably consistent.
