ABSTRACT:
A magnetic head support arm for a disk file comprises a relatively rigid arm structure and a magnetic head suspension assembly fixed at one end to the head support arm having means on the other end to support a transducing head, and having a tapered elongated flat load beam connecting the ends. A means of damping the structure against vibrations comprises a layer of damping material fixed to the elongated flat load beam and a constraining member fixed in contact with the damping material so that the vibration energy is damped due to shear energy absorption in the layer of damping material.
