Abstract
A versatile head positioner stop is provided which bi-directionally limits movement of a head positioning device in a Winchester hard disk drive system. The head positioner stop cushions the impact of the head positioner when it reaches predetermined limits. The head positioner stop has a base and means for mounting the base to the fixed disk drive housing in addition to a pair of side members affixed to the base and provides three distinct stages of resistance for accurately positioning the heads and minimizing the risk of head or disk damage during normal operation and power failure conditions. The head positioner stop is pre-stressed to improve dynamic energy absorption during head positioner crashes.
