Abstract
A swing type structure for a head stack assembly of a disk drive includes a body portion, a coil portion, and at least one actuator arm structure. The actuator arm structure includes at least one elongated column, and a pair of wires in tension. The body portion has a bore defining a longitudinal axis, and the coil portion is cantilevered from the body portion. The elongated column is cantilevered from the body portion in an opposite direction from the coil portion and has a distal end. Each wire is positioned on an opposite side of the elongated column and converges on the distal end such that the elongated column is in compression as a result of the pair of wires.
