  • Reaction mass dual-stage actuator (DSA) and sensor
    Patent number: 6922303
    Abstract: A hard disk drive that has a reaction mass and a transducer that can be used to move and/or sense the acceleration of an actuator arm of the drive. The transducer is coupled to a disk controller that can provide output signals which induce a movement of the reaction mass. Movement of the reaction mass will cause a responsive movement of a head(s) coupled to the actuator arm. The transducer can also provide input signals to the controller that correspond to an acceleration of the actuator arm. The acceleration signal can provide force feedback for a servo system of the drive.
