Abstract
Embodiments of apparatus are directed to a rotational shock tester system comprising a disc drive support system, a drop mechanism and an impact apparatus. The disc drive support system includes a rotation plate, wherein a disc drive is coupled to the rotation plate. The drop mechanism is coupled to the disc drive support system and includes an elevating apparatus, wherein the elevating apparatus elevates and releases the rotation plate which is supporting the disc drive. The impact apparatus is releasably coupled to the drop mechanism and is aligned with the rotation plate such that upon release of the rotation plate, the rotation plate impacts the impact apparatus such that the impact apparatus imparts an angular acceleration to the rotation plate and imparts a rotational shock to the disc drive.
