Abstract
A drive system for capstan driven magnetic tape rolls in which a power belt is trained around a drive wheel and a pair of belt guides. The belt guides are closely spaced relative to the capstan so that the back side of the belt transfers power to the capstan roller while the inner surface of the belt contacts the drive wheel and belt guides. The angular spacing of the belt guides relative to the capstan roller is such that the angle between the axial centers of the belt guides with respect to the axial center of the capstan roller is as large as practical, thereby increasing the frictional surface transferring power from the drive wheel to the capstan roller.
