Abstract: A suspension load beam used for attachment to a slider assembly and an actuation arm in a disc drive for data storage has a rigid middle beam section comprising a rigid bottom layer, a rigid top layer and a composite core layer sandwiched between the bottom layer and the top layer. A method for fabricating a vibration resistant mechanical member used a disc drive subject to high frequency motion operations is also disclosed. The method involves making an integral laminate structure and fabricating the mechanical member from the integral laminate structure. The integral laminate structure has A rigid bottom layer, a composite core layer on top of the rigid bottom layer, and a rigid top layer on top of the core layer so that the composite core layer is sandwiched between the rigid bottom layer and the rigid top layer.

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.
