Abstract
Various embodiments concern a gimbaled flexure having a dual stage actuation structure. The flexure comprises a gimbal which includes a pair of spring arms, a pair of struts, and a tongue between the spring arms. A motor is mounted on the gimbal. The motor comprises a top side and a bottom side opposite the top side. The bottom side of the motor faces the flexure. A stiffener is mounted on the top side of the motor. At least one layer of adhesive is located between the stiffener and the motor and bonded to the stiffener and the motor. The gimbaled flexure includes a slider mounting for attaching a slider, such as to the tongue. The motor bends the struts to move the slider mounting about a tracking axis while the stiffener limits the degree of bending of the motor.
