Abstract
An inertial spring latch with a contact post is disclosed for use in latching an actuator assembly of a data storage device. The actuator assembly includes a contact arm that cooperates with the contact post to restrict movement of the actuator assembly when the data storage device is in a non-operating mode. The inertial spring latch includes a latch body adjacent the actuator assembly, a forward arm extending in a first direction from the latch body and a spring member extending from the forward arm, the spring member supporting the contact post. The contact post inhibits movement of the actuator assembly by decelerating the movement of the actuator assembly upon impact of the contact arm with the contact post. Both the contact post and the spring member deflect to dampen the energy of motion of the actuator assembly, upon impact of the contact arm with the contact post.
