Abstract
Micro-stiffening controls resonance in manufactured devices by reducing the amplitude of resonant vibration due to specific system dependent resonant frequencies. One specific use of the present invention relates to magnetic recording head suspensions wherein the reduction in amplitude, or damping, of detrimental resonant frequencies is achieved by micro-stiffening of specific areas of the suspension. By micro-stiffening the metal of the magnetic head suspension the amplitude of resonant oscillations is reduced at its origin. Thus, resonant oscillations no longer propagate along the entire length of the suspension. The magnetic head does not modulate significantly, resulting in alleviation of the detrimental effects of resonant oscillation on magnetic recording including cross-track error and head to disk spacing modulations.
