  • System and method for tape drive control
    Patent number: 7230788
    Abstract: A system and method for damping the motion of the head of a tape drive is disclosed. The method includes measuring the position of the head over time with a position sensor; damping the motion of the head based on the measured position of the head over time; and tuning the damping by varying a parameter of the position sensor.

  • Position sensors for tape loading mechanism
    Patent number: 6619577
    Abstract: A method of loading a tape from a single reel tape cartridge into a take-up reel. Position sensors detect position of a guide arm as a tape loading mechanism loads and unloads tapes from a single reel tape cartridge. The position sensors are accurate and eliminate problems that occur from small misalignments of hub filler access with the access of the take-up reel. Further, the position sensors enable the hub filler to consistently attach to a leader pin at the end of the tape of the single reel tape cartridge without frequent malfunctions.

  • Tape drive cartridge latching mechanism
    Patent number: 6621657
    Abstract: In an automatic tape loader mechanism, for example for a digital tape storage system, the forces of registration springs intended to engage notches in a tape cartridge are de-rated prior to and/or during insertion of a tape cartridge into the loader. The preferred embodiment utilizes two registration springs mounted on a cartridge shuttle. When the shuttle is in its initial position for loading and unloading of the cartridge, the distal end of each spring engages a ramp formed on the support of the loader housing. This engagement deflects the springs away from the cartridge and thereby reduces the force necessary to insert the cartridge. To reduce scraping, the springs preferably carry rollers to engage the walls and registration notches of the cartridge.
