摘要： A head actuator for a disc drive and storage system having a plurality of discs and a plurality of read/write heads positioned on upper and lower surfaces of the discs. The head actuator includes a plurality of load springs. Each load spring has a plurality of through holes located at its inner end. A head is mounted to the outer end of each load spring for positioning the head on the upper or lower surface of a disc. The head actuator further includes an integrally formed head arm assembly. The head arm assembly has a plurality of parallel head arms integrally formed at their inner ends to a main head arm body member and extended in parallel therefrom such that they can be positioned between corresponding discs of the disc drive and storage system. Each head arm is formed with a plurality of through holes in its outer end for alignment with a plurality of corresponding through holes formed in each head load spring at its inner end. The load springs are connected to opposite sides of the head arms using the aligned through holes of the load springs and head arms. The head load springs are sequentially connected to the head arms in an assembly method using a plurality of screws for directly connecting the outer ends of the head arms to the inner ends of the load springs via two series of through holes of the head arms and the load springs.
