Abstract
A suspension assembly for a magnetic head reduces isolation forces caused by swaging the suspension to an actuator arm of a disk drive. The suspension is formed with a first end, and a second end having an inner periphery which defines an opening. Tabs extend from the inner periphery into the opening. A base plate with a cylindrical hub is welded to the tabs and the hub extends through the inner periphery. Multiple isolation welds formed on the suspension cooperate with the tabs to isolate forces and limit force propagation when the hub is swaged to the actuator arm.
Claims3
A method of swaging a head assembly to an actuator arm of a disk drive for reducing assembly gram load changes, comprising the steps of:
- providing a suspension with an inner periphery and tabs extending from the inner periphery;
- welding a base plate with a hub to the suspension and extending the hub through the inner periphery of the suspension;
- providing an actuator arm with an opening;
- extending the hub through the actuator arm opening;
- and
- swaging the suspension to the actuator arm.
