Zusammenfassung:	A return plate for the voice coil motor of a disk drive is disclosed, wherein the angular positions of the top and bottom plates of the return plate are aligned by employing slot shaped voids and anchoring features. The bottom plate is anchored by a tight tolerance coupling to an actuator mounting boss in the base plate of the disk drive. The angular position of the bottom plate is controlled by a slot shaped hole that couples with a tight tolerance in a narrow dimension to an alignment boss in the base plate. The top plate is anchored to the base plate, and the angular position of the top plate is controlled by a slot shaped standoff that couples with a tight tolerance in a narrow dimension to the alignment boss.
