Passive Vibration Absorption for Extremely High Density Recording Academic Article uri icon


  • A method is proposed for passive vibration absorption in hard-disk drives during transient events such as the coming into proximity of the rotating disk within the context of thermal fly-height control nanotechnology or external shock. The method uses a nonlinear energy sink at the center of mass of the slider that can absorb energy over a wide range of excitation frequencies. Its feasibility and performance are investigated through a 4-degree-of-freedom dynamic model of the head-disk interface used to predict head-disk clearance and vibrations. © 2012 IEEE.
