An improved inertial latching system for the actuator in a disc drive. The inertial latching system of the present invention includes an unbalanced inertial member which rotates in response to translational or rotational mechanical shocks applied to the disc drive. The inertial member rotates in either a first or second direction, dependent on the direction of the applied mechanical shock, and includes corresponding first and second contact surfaces for engaging a cooperative feature on the moving portion of the actuator. The contact surfaces are configured to act as camming surfaces which compensate for tolerance clearances in the latching system and provide latching power proportional to the amount of applied mechanical shock. The inertial member also includes a centering mechanism for returning the inertial member to a passive rest position in the absence of and at the termination of applied mechanical shocks.
