Abstract

Various embodiments concern a dual stage actuation flexure. The dual stage actuation flexure comprises a flexure having a gimbal. The gimbal comprising a pair of spring arms, a tongue between the spring arms, and a pair of linkages respectively connecting the pair of spring arms to the tongue. The dual stage actuation flexure further comprises a pair of motors mounted on the gimbal and a pair of stiffeners respectively mounted on the motors. The dual stage actuation flexure further comprises a slider mounting. Electrical activation of the motors bends the pair of linkages to move the slider mounting about a tracking axis while the stiffeners limit the degree of bending of the motors during the electrical activation.
