  • Actuator system for a disc drive using a piezoelectric assembly
    Patent number: 6757124
    Abstract: An actuator assembly of a disc drive having an actuator arm rotatably mounted adjacent a data disc. The actuator arm includes a piezoelectric assembly configured to displace a data transducer relative to the data disc. The piezoelectric assembly may include a top-left piezoelectric element, a top-right piezoelectric element, a bottom-left piezoelectric element, and a bottom-right piezoelectric element. The actuator arm also includes an hourglass-shaped arm pivot configured to bias the data transducer to a rest position.
    Type: Grant
