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.
