ABSTRACT:
A cantilever magnetic head support arm assembly for a disk file comprises a flat beam structure and a means of damping the structure against out-of-plane vibrations. The damping means comprises a rigid sidebar extending along one longitudinal edge of the beam structure and a layer of compliant damping material connecting the beam structure and sidebar together. Relative motion between the beam structure and sidebar causes elastic shear deformation of the damping layer to absorb the energy of vibration.
