Abstract

The effect of a typical constrained layer damping (CLD) patch on the resonant behavior of a standard Type 13 magnetic recording head suspension is determined and compared with that of a specially designed tuned-CLD patch, using both numerical and experimental techniques. In particular, attention is focused on damping the first in-plane bending mode, or sway mode, of the load beam. In addition, a specification for the real modulus of a damping gel is given which, if realized in a suitable material, would enable the application of the tuned-CLD approach to magnetic head suspensions
