摘要： A structure for a load beam used in hard disk drive devices includes an asymmetric structure. The load beam exhibits longitudinal asymmetry (i.e., is asymmetric along its long axis) in regard to the weight distribution, but has a center of mass that lies along its longitudinal axis due to the provisioning of counterbalancing features, such as the addition of material, the removal of material, or a combination of adding material and removing material, or the use of an asymmetrical damping layer.

摘要： A suspension assembly for a hard disk drive includes at least two spring extensions that couple to a proximal portion of a load beam. These spring extensions are disposed by a vertical offset and couple to the load beam on opposite sides of a longitudinal axis of the load beam. The method for operating a disk drive apparatus includes following by a suspension assembly from a reference position to a second position a vertical movement of a rotating disk. The suspension assembly is predisposed to move from the reference position to the second position by the vertical offset. A read/write head coupled to the suspension assembly is in closer alignment to a selected track during the vertical movement in the second position than if the first and second spring extensions were disposed to be co-planar.

摘要： Techniques for reading and writing information onto a hard disk drive are provided. According to an embodiment of the present invention, a suspension assembly for a hard disk drive includes a load beam having a mounting region, a first spring extension on a first side of the load beam, and a rigid region. The suspension assembly also includes a hinge member having a second spring extension coupling the rigid region and the mounting region on a second side of the load beam. First and second spacers are disposed between the hinge member and the mounting region of the load beam and between the hinge member and the rigid region of the load beam, respectively. A vertical offset between the first and second spring extensions predisposes the rigid region to move from a first position to a second position in response to a disk flutter.
