ABSTRACT:
A microactuator used for selectively altering a position of a transducing head carried by a slider in a disc drive system with respect to a track of a rotatable disc having a plurality of concentric tracks. The microactuator is of the type comprising a piezoelectric element. A polymer coating encapsulates all exposed surfaces of the piezoelectric element.
