Abstract
An actuator for a magnetic head of a disk device has a rotating arm constructed of resin. The arm is supported rotatably in a housing on an electrically conducting shaft, and a magnetic head supported by a supporting member at one end of the arm is moved to various positions above the magnetic disk when the arm is rotated by a rotating mechanism. An electrically conducting mechanism conducts static electricity from the supporting member of the magnetic head to the shaft so that static electricity is prevented from accumulating on the head supporting member of the resin arm or in its vicinity.
