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.
Claims16
A magnetic head assembly comprising:
- a head suspension having a first end and a second end, the second end having an inner periphery defining an opening;
- a magnetic head attached to the first end for transducing data signals;
- a base plate having a hub, the base plate being welded to the second end, wherein the hub extends through the inner periphery;
- a plurality of tabs attached to the inner periphery, said tabs extending into said opening, said tabs disposed uniformly and evenly spaced around said hub;
- a multiplicity of force isolation elements disposed uniformly and spaced evenly adjacent to said hub to isolate forces imposed on the suspension by the base plate;
- whereby said tabs and force isolation elements cooperate to isolate forces and thereby limit force propagation during swaging of said suspension to an actuator arm.
