Abstract
A compressive limit stop for limiting travel of an actuator assembly of a data storage device is disclosed. The compressive limit stop separates a first pole piece from a second pole piece of the data storage device, each pole piece adjacent the actuator assembly, the compressive limit stop includes a rigid body with a top flange adjacent the second pole piece and a bottom flange adjacent the first pole piece, an inner portion having a diameter less than the diameter of the top flange disposed between the top and bottom flanges forming a channel between the flanges and a compressive sleeve with an inner wall adjacent each flange while enclosing the channel to form a gap between the inner portion and the inner wall. The compressive sleeve deflects and compresses between the actuator assembly and the inner portion to decelerate movement of the actuator assembly, upon impact of the contact arm with the contact post.
