ABSTRACT:
A flexure for use in a head gimbal assembly comprising a single narrow torsion beam that connects a suspension load beam to a slider support member. The flexure is centered underneath a read/write slider and may be comprised of a laminated material having a conductor layer, a dielectric layer and a support layer. A plurality of electrical leads may be formed in the conductor layer for attachment the slider. The slider is mechanically attached to the slider support member by a first set of solder balls the height of which create a space for accommodating deflections of the flexure and allowing the electrical leads to pass underneath the slider. Electrical connections to the slider are made using a plurality of right angle fillet joints between the slider and a second set of solder balls on the slider support member. The shape of the torsion beam may be varied to yield different levels of stiffness to pitch, roll and yaw movement of the flexure.
