Energy absorbing disc travel limiter

摘要

An energy absorbing disc travel limiter which not only mechanically defines a limit to the extent to which a disc in a disc drive can be axially displaced in response to applied mechanical shocks, but which also acts to damp the shock-induced motion of the discs, thus preventing contact between the discs and the actuator head mounting arms. The amount of damping provided by the disc travel limiter is determined by selection of the material of the disc travel limiter and selection of certain dimensions of the disc travel limiter.
