ABSTRACT:
The invention includes a method of attenuating resonance frequency modes in head suspensions, which does not significantly increase the weight of the head suspension. The invention provides a way to control the head deflection from the disk surface, which helps minimize damage from head slapping. The invention includes a basic head suspension infrastructure for which vibration resonance can be predictably controlled.
