ABSTRACT:
A suspension for positioning a floating read-write head assembly over selected tracks on the surface of a rotating data storage device. It includes a planar and resilient load beam having a proximal end portion that may be constructed for attachment to an actuator arm, a gimbal region located at a distal end portion constructed for supporting a read-write head assembly for gimballed motion relative to the surface of the data storage device, a spring region between the proximal end portion, and a rigid floor region located between the spring region and the gimbal region. The suspension also includes a sheet material shell region having side wall regions supporting a ceiling region over a face of the rigid floor region of the load beam. The wall regions may include longitudinally extending edge flanges projecting generally away from the ceiling region and from the rigid region, lip edges to facilitate attachment, and lift surfaces. The wall regions attach the shell to a face of the floor region of the load beam to cover at least the floor region and form into a stiffened monocoque region encasing a cavity between the load beam and the shell region. A method for manufacturing the suspension is also disclosed.
