Abstract
An actuator assembly for a magnetic storage system wherein the end arms are dynamically tuned to reduce the modes of vibration on the actuator to improve the performance and stability of the actuator assembly in the magnetic storage system. In one embodiment, the upper and lower outer arms of the actuator assembly are thinned in the same or similar locations. In another embodiment, the upper and lower outer arms of the actuator assembly are notched at high strain energy points to reduce the stiffness of the outer arms. In still another embodiment, the upper and lower outer arms of the actuator assembly are both notched and thinned at the same or similar locations.
