An actuator arm latch assembly for a disk drive is disclosed which restrains
movement
of a disk drive actuator arm assembly during exposure of the disk drive to a shock
event. In one embodiment, the actuator arm latch assembly is activated by the disk
drive being exposed to a shock event that is directed along/about a first shock
axis (e.g., within a reference plane that contains a disk drive base plate), and
also is activated when the disk drive is exposed to a shock event that is directed
along/about a second shock axis that is both non-parallel and non-colinear with
the first shock axis (e.g., within a reference plane that is disposed at an angle
to the disk drive base plate, and including perpendicular thereto).
