ABSTRACT:
A slider assembly for selectively altering a position of a transducing head with respect to a rotatable disc includes a slider body having opposing leading and trailing edge surfaces, opposing top and bottom surfaces, and opposing first and second side surfaces. The slider body is arranged to be supported by a support structure over a surface of the rotatable disc. A slot is formed in the slider body proximate the trailing edge surface, forming a hinge joining a distal portion of the slider body adjacent the trailing edge surface to a main portion of the slider body. The transducing head is carried by the distal portion of the slider body. A microactuator is attached to the slider body adjacent to the hinge. The microactuator is responsive to electrical control signals to selectively bend the hinge to alter the position of the transducing head with respect to the main portion of the slider body.
