ABSTRACT:
A belt-driven tape cartridge with reduced tape pack deformation and more spatially homogeneous tape tension. The belt driven tape cartridge has a supply side tape hub and a winding side tape hub both rotatably mounted on the base. The tape is wound around the hubs to form a tape pack about each hub. A drive roller is rotatably mounted on the base. First and second rollers are rotatably mounted on the base. The drive belt is engaged on the drive roller, the tape pack on the supply side tape hub, the first and second corner rollers, and the tape pack on the winding side tape hub. The pack belt is engaged between the first and second corner rollers and disposed on the inner side of the drive belt. The drive belt has a width less than a width of the pack belt such that tape pack deformation is reduced and the tape tension is more spatially homogeneous.
