ABSTRACT:
A vertical displacement limit stop or a crash stop is provided in a disk drive for preventing contact of the work function members such as air vanes or the arms of an armstack, or the flexure members, when the actuator is in locked position, with adjacent track surfaces of the disks, in the presence of shock forces. Vertical displacement stops on the work function members each have an impact face which confronts an adjacent surface of a disk. These impact faces each project above any other part of the associated work function member in a position overlapping and confronting the surface of a disk at its outer peripheral edge, outside of tracks recorded on the disk, to prevent other parts of the work function member from contacting the surface of a disk in an area in which tracks are recorded.
