Abstract
A vibration damper for a disk drive suspension includes a viscoelastic damping layer, a substantially stiffer polymer constraining layer, and a metal layer interposed between the viscoelastic layer and the polymer constraining layer, such as a thin layer of aluminum vapor deposited onto the polymer constraining layer. The metal layer hides irregularities in the viscoelastic layer as that viscoelastic layer is adhered to the suspension without introducing potentially contaminating mineral particles into the polymer constraining layer.
