Abstract
A rotary actuator for a disk drive includes a pivotally mounted carriage and a stacked arrangment of magnetic transducer support arms extended away from the carriage, each arm supporting a magnetic transducing head at its free end for arcuate travel as the carriage pivots. A circuit board, for connecting the transducing heads to read, write and control circuitry, is mounted along one side of the head arm assembly, secured to the carriage. A section of the circuit board extends away from the carriage in cantilever fashion toward the transducing heads. A preloaded retaining spring is secured to the carriage on the opposite side of the circuit board from the carriage, and includes a plurality of load arms that bear against the cantilevered portion of the circuit board, continually biasing the board, and an electrically insulative spacer mounted to the board, against the transducer support arms.
