A data storage tape cartridge incorporating a belt-driven design with improved performance characteristics. The tape cartridge includes a housing, first and second tape hubs, a storage tape, a drive roller, first and second corner rollers, and a drive belt. The housing defines a head access window. The first and second tape hubs are rotatably mounted within the housing. The storage tape is wound about the first and second hubs to form first and second tape packs thereabout. The drive roller is also rotatably mounted within the housing. Similarly, the first and second corner rollers are rotatably mounted within the housing. The drive belt is stretched about the drive roller, the first and second tape packs, and the first and second corner rollers. Finally, the first and second hubs are symmetrically arranged relative to the head access window. This symmetrical arrangement optimizes cartridge performance. Unlike prior art belt-driven tape cartridges, the tape cartridge of the present invention is not driven by a capstan or similar device, but instead is spline-driven.
