Abstract: A method and apparatus of forming a battery enabled flexible circuit. The invention includes forming a first insulating layer and positioning a battery on the first insulating layer, the battery having at least a first and a second terminal. A second insulating layer is then formed on the first insulating layer and the battery. The second insulating layer has vias that are in electrical contact with at least one of the first and the second terminals.

Abstract: A disk drive system includes a base, a disk rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information representative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly also includes an arm which has a first layer of material including a plurality of elongated fibers orientated in a first direction, and a second layer of material including a plurality of elongated fibers orientated in a second direction. The first and second layers are part of a composite material. The transducer is attached to said arm. The resulting actuator arm has a resonant frequency that can be varied or moved or shifted by varying the direction of the elongated fibers in the second layer with respect to the direction of the elongated fibers in the first layer.
