Head support arm and head/arm assemblies for disk files.

摘要

A cantilever head support arm for a disk file comprises a flat beam structure (10) and a means of damping the structure against out-of-plane vibrations. The damping means comprises a rigid side bar (14) extending along one longitudinal edge of the beam structure and a layer (16) of compliant damping material connecting the beam structure (10) and side bar together. Relative motion between the beam structure and side bar causes elastic shear deformation of the damping layer (16) to absorb the energy of vibration.
