ABSTRACT:
A disk drive having a disk stack and a movable actuator movable between position limits for moving one or more transducers between inner and outer radial limits with respect to the disk stack, established by a crash stop structure having at least one crash stop arm or projection for engaging the movable actuator and limiting actuator travel. The crash stop projection is stiff in the direction of actuator impact forces and is also displaceable from crash stop position in a direction different from the direction or impact forces, but biased to crash stop position, to permit forcible displacement of the crash stop projection in the different direction so that the actuator may be moved therepast during actuator installation or removal when assembling or disassembling the disk drive.
