    • A drive unit for driving magnetic tape held within a tape cartridge, the tape cartridge engaged to the drive unit in abutting fashion. The drive unit provides an elastomeric drive belt which surrounds a drive pulley, a tensioning pulley and an engagement pulley, the engagement pulley resiliently urging the drive belt against a cartridge roller located within the cartridge which progresses the magnetic tape within the cartridge. The drive pulley is driven directly by a motor which progresses the belt around the three rotating pulleys. The arrangement eliminates the need for a separate friction roller arranged above the drive belt by using the drive belt itself to drive the cartridge roller.
    • 用于驱动保持在带盒中的磁带的驱动单元,所述带盒以相邻的方式接合到驱动单元。 驱动单元提供弹性体驱动带,其围绕驱动滑轮,张紧滑轮和接合滑轮,所述啮合滑轮将驱动带弹性地推动抵靠位于所述盒内的盒式滚筒,所述盒式滚筒推进盒内的磁带。 驱动皮带轮由马达直接驱动,马达使皮带围绕三个旋转皮带轮进行。 该布置消除了通过使用驱动带本身来驱动盒式滚筒而需要布置在驱动带上方的单独的摩擦辊。
