ABSTRACT:
The rotary actuator comprises a transducer head connected to an E-block, a base, and a rotating data-storage disk journalled to the base. In addition, the rotary actuator comprises a top plate having a first pivot bearing socket, a bottom plate having a second pivot bearing socket, and a pivot shaft. The first pivot bearing socket is placed oppositely facing the second pivot bearing socket defining an axis therebetween. The pivot shaft is mounted between the first pivot bearing socket and the second pivot bearing socket along the defined axis, wherein the pivot shaft is embedded within a pivot center of the E-block having an axis of rotation for incrementally rotationally positioning the transducer head at data locations defined on a surface of the rotating data-storage disk. The axis of rotation of the E-block being generally coaxial to the defined axis of both bearing sockets.
