Abstract
A tape cartridge of the belt drive type, wherein an elastomeric member is coupled to the drive belt to be continually deformed by the drive belt, so that hysteresis energy losses in the elastic member create drag on the drive belt. In one cartridge, the belt guide rollers, about which the belt extends, have rubber-like cores. In a second cartridge, a thick rubber-like auxiliary belt extends around the belt guide rollers so that the auxiliary belt is driven by the drive belt as it rotates the guide rollers. In a third cartridge, a rubber-like auxiliary roller presses against a belt guide roller.
