ABSTRACT:
Method and apparatus for an improved insulating wire guide for a disc drive actuator assembly. The insulating wire guide is integrally formed with an actuator arm and comprises a rigid, non-conductive material formed onto the actuator arm, the wire guide having a base portion on which head wires rest and tabs extending from the base portion to form a channel through which the head wires are routed. The wire guide and actuator arm are formed from an extrusion having a cross-sectional shape substantially that of the actuator arm, the extrusion including dams forming a channel along one side of the extrusion. The non-conductive material is applied to the extrusion, substantially filling the channel, and, after the non-conductive material is cured, the extrusion and the cured non-conductive material is machined to provide the desired configuration of the actuator arm and the wire guide.
