Abstract
A disk drive actuator assembly adapted for assembly in one of several configurations from a single line of modular components without a manually-supervised aligning step. The actuator improves manufacturability and inertia by introducing a common set of self-aligning modular piece parts. Each of several self-aligning modular components can be used to assemble any of several different actuator assembly designs. That is, a head-stack assembly (HSA) providing from one to six heads can be assembled using elements selected from single set of standardized modular components. The assembly process relies entirely on the self-aligning features of the standardized modular components, thereby eliminating the elaborate and error-prone manual assembly and alignment procedures known in the art.
