ABSTRACT:
An actuator assembly for a disk drive system includes an actuator pivotally mounted to a shaft, and a coil assembly. A counterbalance portion of the actuator provides a recess wherein a portion of the coil assembly is slidably inserted. The coil assembly includes a bobbin which has a dovetail portion having at least two precision positioning surfaces which, when placed within the counterbalance recess, interact with corresponding precision positioning surfaces provided within the counterbalance recess. In order to accurately position the coil assembly with respect to the actuator, an outward force is applied to the coil assembly perpendicular to the pivot axis to cause facing pairs of the precision positioning surfaces of the coil assembly and the counterbalance recess to bear against one another, and align a dowel/pin alignment passageway extending through the counterbalance with a dowel/pin recess provided in the bobbin. A dowel is then placed through the alignment passageway and into the dowel/pin recess to hold the actuator and coil assembly in the preferred configuration while an adhesive is injected into the spacing between the bobbin and the counterbalance recess. No adhesive is injected between the precision positioning surfaces bearing against one another. The dowel is subsequently removed and replaced by a stop pin.
