Abstract
A coupling for driving a magnetic tape reel uses the interface between a flat surface on the coupling and datum pads on the reel to locate the reel. The coupling includes a drive ring with ring teeth located around a drive shaft. The ring teeth engage mating teeth on the tape reel. The coupling also includes a datum ring having an annular surface located about the drive shaft. The annular surface contacts datum pads on the tape reel to axially position the tape reel relative to the drive shaft.
