A swing-type actuator (10) includes a coil (20), at least one arm (40) and a the rmoplastic body (50) joining the coil (20) and arm (40). The arm (40) is preferably a planar stamping having an opening (43) to whi ch the read/write head is mounted. A body (50) is molded around portions of the arm (40) and coil (20). A journal (52) is formed in the b ody (50) for receiving a shaft and bearing on which the actuator (10) pivots. A grounding pin (40B) extending through the arm (40) preve nts static charge build-up. Alternatively, a portion of the arm (40) may extend into the journal (50) to contact the bearing. In another emb odiment, the arm (140) includes a plastic portion (70) and a metal mounting pad (80). The plastic portion (70) may be formed of electricall y conductive material to prevent static charge build-up.
