US Patent 9165578 Swage mount for hard disk drives

A swage mount is provided for attaching a head suspension assembly to a head actuator arm for a hard disk drive. The swage mount has a flange body with a thickness for providing clearance from the underlying disk. The swage mount may have a tip for in-plane movement. The tip may be ‘T’ shaped. The tip has a thickness that is greater than the thickness of the flange body for withstanding out-of-plane loads and for enhancing performance of the hard disk drive, for example, during reading/writing of data using the head. Mass properties of the swage mount, the twisting/bending yield load, modal frequency responses, and other performance metrics are analyzed to design the dimensions of the swage mount having favorable in-plane compliance and superior out-of-plane robustness.
