ABSTRACT:
A method and apparatus is provided for attaching magnetic disk drive actuator arms to read/write head suspension members. The arms and suspensions have through holes. The suspension member has a boss on its surface surrounding its through hole. To attach a suspension to an actuator arm, the hole in the arm is brought into alignment with the hole in the suspension such that the boss on the suspension protrudes into the hole in the arm. An expandable pin is inserted into the boss and holes. The expandable pin is then forced to expand radially, causing the boss to expand into an interference with the hole in the actuator arm, thus attaching the suspension and the arm. Because the forces applied to the actuator arm are limited to being axially applied to the walls of the hole, cracking of the actuator arm is avoided. Thus, actuator assemblies with ceramic actuators are provided.
