Embodiments of the present invention include A head suspension assembly for a data storage device comprising a load beam and a Femto flexure coupled to the load beam, wherein the Femto flexure is a laminate structure comprising a support layer, the flexure comprising a plurality of symmetrical flexure legs, each of the flexure legs substantially hourglass shaped.

Flexure leg optimization shapes for lateral stiffness

A suspension for a disk drive includes a mount plate adapted to mount to a primary actuator, a functional end portion adapted to carry a slider, and a hinge disposed between the mount plate and the functional end portion. A mounting configuration is provided on the mount plate for mounting the suspension to the primary actuator. A pair of secondary actuators are mounted in longitudinally overlapping relationship with the mounting configuration so as to minimize the impact of the secondary actuators on suspension length. The secondary actuators are operatively connected to the hinge for producing sway displacement of the slider.

Dual stage suspension with PZT actuators arranged to improve actuation in suspensions of short length

A technique for electrically interconnecting a disk drive suspension assembly and a micro-actuator mounting a transducer-carrying slider. A first set of termination pads is provided on a generally planar surface of the micro-actuator, adjacent a front edge portion of the micro-actuator. A set of leads is provided on the suspension assembly so as to extend generally orthogonally to the first set of termination pads and in adjacent relationship therewith. Electrical connections are provided between the first set of termination pads and the suspension assembly leads. A second set of termination pads can be provided on the micro-actuator planar surface adjacent to a front edge portion of the slider and a third set of termination pads can be provided on the slider front edge portion. The second and third sets of termination pads are then electrically connected.

Micro-actuator integrated lead suspension head terminations

A suspension assembly is designed to carry a slider and read/write head elements in a magnetic data storage device. The suspension assembly is formed from a composite laminate structure that includes first, second, third, fourth and fifth material layers. The layers are arranged such that the second layer is disposed between the first and third layers, and the fourth layer is disposed between the third and fifth layers. The laminate structure is configured using a suitable removal process, such as partial chemical etching, to define a mount plate, a hinge, a load beam functional end, and an electrical lead system. The laminate structure may be further formed with a flexure gimbal system that comprises the third, fourth and fifth layers.

Weld free high performance laminate suspension

A method for making a suspension system comprising a multiple layer flexure, a load beam and an arm. The load beam extends from the tip of the suspension all the way back to the rear of the arm. Datum holes are located in the load beam such that during assembly all reference points are made from the single load beam piece.
