Abstract

An assembly and method for micropositioning a disc drive head is described. An implementation of the assembly includes a gimbal, a piezoelectric element bonded to the gimbal and electrically connected to a voltage source, and a slider connected to the piezoelectric element. The assembly may also include at least a second piezoelectric element bonded to the gimbal and connected to the slider. The piezoelectric elements may be made of PZT material, and each may be in a monomorph or bimorph configuration.
