摘要： 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.

摘要： The coaxial reel tape cartridge uses a lengthy tape path within the tape cartridge to reduce the stresses on the tape medium as it is transported between the two reels. The tape reel lock mechanism locks the two tape reels together to prevent rotation of the reels with respect to each other when the tape cartridge is removed from the tape drive. The lock mechanism also locks the tape reels to the exterior housing to prevent any rotation of either tape reel. This lock mechanism enables to tape cartridge to implement mid-point loads.

摘要： A spool system for packing tape on a hub. The spool has upper and lower flanges on the hub, and a flexure positioned on the hub between the two flanges. The flexure is normally parallel to the flanges, but when a force is applied to the tape lead-in edge of the flexure, that edge of the flexure is pressed toward one of the flanges. This causes the tape lead-in side of the spool system to have a wider opening than the tape packing side of the spool system. The width of the space on the tape packing side is preferably equal to or narrower than the width of the tape to be packed, so that the flexure presses against the edge of tape as it loads, reducing stagger of the tape.

摘要： An apparatus for positioning a transducer includes a fixed frame and a moving frame movably associated with the fixed frame such that the moving frame is movable between a plurality of discrete positions relative to the fixed frame. A carriage is movably associated with the moving frame and has the transducer mounted thereon. The apparatus further includes an actuator associated with the carriage. The actuator is operative to move the moving frame to a selected discrete position of the plurality of discrete positions, and is further operative to move the carriage relative to the moving frame when the moving frame is in the selected discrete position.

摘要： The reaction force decoupling system, as implemented in a tape drive, reduces the motion that is coupled back into the tape cartridge from the reaction force that is generated by the operation of the read/write head actuator. The read/write head actuator consists of a magnet assembly which produces a large magnetic field in an annular gap and a coil of wire which operates freely in the magnetic field of the gap. The magnet assembly is mounted to the base of the drive and the coil is attached to the read/write head carriage. When current is applied to the coil, a force is produced between the coil and the magnet assembly to move the read/write head carriage. The magnet assembly is disconnected from the base of the drive and mounted on dual flexures arranged in a four bar linkage parallel guide arrangement. The reaction forces that are generated by the operation of the read/write head actuator must deflect the flexures to apply a load to the base of the drive. As the flexures are deflected, the magnet assembly is guided to remain coaxial with the coil. At low frequencies, the same reaction force is still applied to the base of the drive through this apparatus but above the resonant frequency of this apparatus, the reaction forces are attenuated with the result that the servo loop instability is reduced.

摘要翻译： 如在带驱动器中实现的反作用力解耦系统减少了由通过读/写头致动器的操作产生的反作用力而耦合回到带盒中的运动。 读/写头致动器由在环形间隙中产生大的磁场的磁体组件和在间隙的磁场中自由操作的线圈组成。 磁体组件安装在驱动器的底座上，线圈连接到读/写头托架。 当电流施加到线圈时，在线圈和磁体组件之间产生力以移动读/写头托架。 磁体组件与驱动器的基座分离，并安装在布置在四杆连杆平行导轨装置中的双挠性件上。 由读/写头致动器的操作产生的反作用力必须使挠曲件偏转以将负载施加到驱动器的底座。 当挠曲件偏转时，磁体组件被引导以保持与线圈同轴。 在低频时，相同的反作用力仍然通过该装置施加到驱动器的基座上，但高于该装置的谐振频率，反作用力被衰减，结果是伺服回路的不稳定性降低。
