Abstract
A conductive, carbon-filled acetal resin capstan within a belt driven tape cartridge is rotatably supported by a pin and includes a cylindrical outer surface for engaging a drive belt. The capstan is electrically conductive to dissipate static electrical charges and includes a polytetrafluoroethylene-filled acetal resin sleeve interposed between the pin and the capstan to increase the wear resistance of the capstan where it frictionally engages the cartridge.
