Abstract
A head actuator assembly includes a coarse positioner base assembly that is mounted on a guide shaft and an anti-rotation shaft and provides increased structural rigidity due to a four-point support and spring loading of the coarse positioner base against the anti-rotation shaft. A two-part head-carriage and voice coil holder system permits different materials to be used for the head-carriage and the voice coil holder, obviating structural problems of a single-structured head-carriage and coil-holder system. A flexible printed circuit bracket eases manufacture and allows flexible printed circuits to be slid into the bracket and retained in place without the need for locating tabs and screws.
