ABSTRACT:
A tape cartridge, a cartridge-drive system, and a method of operation for aligning spools inside the tape cartridge with fixed center drives. The spools are allowed to slide relative to a baseplate allowing them to move in a direction normal to their axis of rotation to account for axial misalignment with the fixed center drives. Posts maintain the spools in close proximity to the baseplate. The fixed center drives have a flexible joint to account for angular misalignments of the spool and drive axes, and to account for spool-to-drive distance variations along the axis of rotation. Each spool and drive have a ring of triangular shaped teeth that self-align when engaged. Thrust bearings may be disposed between the spools and the baseplate to minimize friction. Each spool may include a normally engaged locking clutch mechanism to reduce the possibility of tape spillage during handling. The clutch is disengaged by engagement with an annular boss on the drive.
