Abstract
Various embodiments concern a head suspension system having a load beam. The lead beam comprises a metal base having a proximal portion and a distal portion. Two opposing rails extend along the proximal and distal portions. The load beam has a void in the metal base separating the proximal portion from the distal portion, the void extending between the rails. A pair of microactuators is coupled to each of the proximal portion and the distal portion such that each microactuator extends across the void. The microactuators bend the rails to move the distal portion along a X-Y plane relative to the proximal portion. Additionally, the rails stiffen the load beam to resist movement between the first portion and the second portion along a Z-axis.
