2134352 9324928 PCTABS00028 A drive belt (18) for use in a tape cartridge (10) including a drive belt wound around a drive roller (20), two guide rollers (22, 24), and a tape pack (17). The belt has a coating (42) on the face of the belt that contacts the rollers. The coating includes carbon black and aluminum oxide particles dispersed in a polymeric binder. The coating on the belt is electrically conductive and has a resistivity of less than 400 ohm-cm. The coated belt minimizes wear on the rollers, voltage buildup, and electrical discharge within the cartridge. This reduces the number of transient errors that occur when reading and writing the tape (16). The tape cartridge may also include a metal pin (36) that contacts the coated face of the belt, thereby providing improved tape tension.
