ABSTRACT:
A base plate is used to attach the head/gimbal assembly of a disc drive to an actuator arm. The base plate has a boss which fits into an opening in the actuator arm. In one embodiment, the boss includes a plurality of raised portions defining a cylinder having a relaxed outer diameter greater than the inner diameter of the opening in the actuator arm. The outer surfaces of the plurality of portions engage the inner surface of the actuator arm to elastically deform and conform to and bias against the inner surface of the actuator arm, thereby providing a connection with superior holding friction, and retention torque.
