ABSTRACT:
Closer spacing of the disks in a disk stack of a disk drive is achieved by joining together the reinforcing plates, sometimes called swage plates, of pairs of load beams of the actuator arm structure to form a transducer suspension assembly of an integrated pair of load beams, each load beam having a distal end flexibly mounting a transducer The transducer of each integrated load beam pair are aligned with each other and face in opposite directions. A load beam extension at the load beam end opposite the distal end of each extends beyond the reinforcing plate. These load beam extensions in each transducer suspension assembly are spaced apart by the thickness of the two reinforcing plates and span the thickness of an actuator arm of the actuator arm structure. The load beam extensions are joined to the opposite faces of the actuator arm. The transducers fit between and confront the surfaces of adjacent axially spaced disks in the disk stack. Joining of the load beam extensions to the opposite faces of the actuator arm may be accomplished by bonding agents such as adhesives, swaging, or by welding, the latter where both the actuator arm and the load beams are of materials that may be welded together.
