ABSTRACT:
A low profile, miniaturized rigid disk dam storage drive includes a micro-swaged connection that mounts the transducer carrying load beams to the respective actuator arms. The micro-swage plate, that is laser welded to the load beam, includes a swage boss that does not exceed 0.3 millimeters in length. The outer periphery and the distal end surface of the tubular swage boss are tapered to counteract rotation and shearing of the boss during swaging. In applications where the smooth exterior swage boss surface does not provide sufficient torque-out capability, the periphery of the boss is formed with axially extending irregularities to enhance the torque-out capability without increasing the pull-out force that would be necessary for disassembly and rework. The preswaged boss configuration includes frusto-conical peripheral and distal end surfaces to afford a swaged configuration with a generally radial end surface and maximum swaged contact through the available length of the swage boss.
