Abstract
An actuator for a disk drive. The actuator includes an actuator body defining an axis of rotation and including a body lateral surface disposed generally parallel to the axis of rotation. The actuator further includes an actuator arm extending from the actuator body. The actuator arm includes an arm base disposed adjacent the actuator body. The actuator further includes a coil support extending from the actuator body opposite the actuator arm. The coil support includes a coil support base disposed adjacent the actuator body. The actuator further includes a constrained layer damper disposed upon the body lateral surface extending from the arm base to the coil support base for mitigation of resonant vibration of the actuator arm and the coil support.
