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： A data cartridge shuttle apparatus (100) is used to permit a robotic hand (40) to insert and remove a data cartridge (246) into and out of a manual cartridge drive mechanism (20). A pawl and lever linkage (104) is rotated to open and close a handle (26) of the tape drive mechanism by contact with a pawl stop (134), which is mounted on a spring-biased sliding block/plate assembly (106). The sliding block/plate assembly has a triangular clasp (228) that engages the data cartridge for extraction of the tape cartridge from the drive bay to a point where the robotic hand can grasp and remove it.

摘要： A pass thru port, for use in an automated cartridge library, is capable of transferring a cartridge from one module of the automated cartridge library to another module of the automated cartridge library without the use of motors or other powered devices. A transfer cell accepts and holds a cartridge to be transferred from one module to another module. A spring loaded toggle mechanism operates to hold the transfer cell at one of the modules until operation of the pass thru port is initiated. The robot arm in either one of the modules is used to depress a lever on the pass thru port. Depression of the lever loads a move spring mechanism. When the lever is released by the robot arm, the force of the move spring mechanism overcomes the force of the toggle mechanism. This causes the transfer cell, holding a cartridge, to be rotated from one module to the other module. There are no separate motors or electrical devices associated with the pass thru port.

摘要： A system prevents an excessive force from being applied to a handle of a tape drive. The system provides a base coupled to the handle of the tape drive. A lever assembly engages the base to move the handle when a force equal to the force required to move the handle is applied to the lever assembly. The lever assembly disengages the base when a force in excess of the required force is applied to the lever assembly and the force is not applied to the handle.
