摘要： A cartridge position fixing arrangement within a tape drive reduces vibration of the cartridge by fixing the vertical positioning of the tape reel axles between top mounted retaining springs pressing directly onto the cartridge above the reel axles in opposition to the tape drive motors engaging lower ends of the reel axles for rotating the axles. Each hub axle is journaled with a relatively high force at a bearing that may be formed in the upper wall of the cartridge. A reel axle locking arrangement is provided which, when the cartridge is unloaded from the tape drive, locks the position of each reel axle and centers each reel axle properly for future engagement with motor spindles of the tape drive. In one embodiment, a planar engagement between each motor spindle and each reel axle is provided.

摘要： A spring loaded tape transversal tension control device is provided to equalize tape tension across the transverse cross-section of a tape to provide a more stable tension throughout the tape such that a reduction in maximum tape tension can be achieved. The device includes a central spring and an outer spring for rotationally balancing tape tension by pivoting the device under spring force to press onto, or retract from portions of the tape.
