Abstract
An actuator for a PCMCIA DASD incorporates a tie bridge for stabilizing the support arms of the actuator while at the same time not increasing the largest radial dimension of the actuator drive motor beyond that of the radial dimension for the exterior of the coil. The tie bridge is disposed above, below, or both above and below the coil of the actuator drive motor. This space otherwise unused is now advantageously utilized, while additionally creating benefits in the design and the operation of the DASD. A crash stop and latch surface are incorporated into the structure of one of the support arms supporting the coil in such a way that the forces encountered by the actuator upon forcible engagement with a rigid structure within the DASD housing are absorbed and thereby reduced to values less than critical failure values.
