摘要： A voice coil driven positioner is provided for positioning the magnetic head of a tape drive relative to the tape of a removable tape cartridge. The head positioner includes a low-mass carriage that supports the head on one end and the voice coil on an opposed second end. A low friction guide mechanism guides the carriage along a precision movement path that carries the head across tracks of a supplied multi-track tape and simultaneously carries the voice coil through a flux field generated by a stator. A movable magnet is attached to the carriage and located within the hollow of the voice coil for reciprocating into a hollow passageway of the stator together with reciprocation of the voice coil into another hollow of the stator. A flux detector is attached to the stator and located compactly within the hollow passageway of the stator for detecting the position of the magnet. A programmable lookup table converts measurement signals output by the flux detector into pre-calibrated, head-position indicating signals. A platform is provided on the carriage for mounting an interferometer prism used during calibration.

摘要： A method and apparatus for loading tape from a single reel tape cartridge into a take-up reel. The hub filler is securely and releaseably attached to the take-up reel upon the hub filler entering the take-up reel. This attachment provides adequate securement between the hub filler and the take-up reel for the tape to be wrapped around the take-up reel during loading of the tape without the hub filler partially ejecting from the take-up reel. By preventing the hub filler from partially ejecting from the take-up reel, damage to the tape and the tape drive loading mechanism is mitigated. Upon unloading of the tape from the tape drive, the hub filler can be readily released from its attachment to the take-up reel.

摘要： A tape drive for accommodating tape cartridges of different sizes and capacities is provided with a drive mouth and a movable door opening mechanism within the drive mouth. The movable door opening mechanism opens a cartridge door of a tape cartridge as it is inserted into the drive mouth. The movable door opening mechanism remains in a first position during initial insertion of a tape cartridge until the cartridge door of the tape cartridge is open, and moves to a second position during further insertion of the tape cartridge to accommodate that tape cartridge within the drive mouth.

摘要： Apparatus for fine positioning a tape head relative to a head carriage that is coarsely positionable by a lead screw. The fine positioning apparatus includes parallel first and second resilient support beams oriented generally parallel to the direction of tape travel and having their ends fixedly secured to the head carriage so as to be deflectable in a direction transverse to the direction of tape travel. The centers of the parallel first and second support beams have their centers secured to a tape head frame which contains the tape. A linear motor drives the tape head frame against the resilience of the first and second resilient support beams in response to a drive signal which, for example, is derived from tracking error information produced pursuant to reading of servo information on tape. Pursuant to the displacement of the tape head frame against the resilience of the support beams, the magnetic tape head is moved along a linear path transverse to the tape travel direction. For operation with tapes without servo information on tape, a piezoelectric transducer detects the deflection of one of the support beams and provides an output which is utilized to provide damping of the natural resonance the spring/mass system that includes the first and second resilient support beams and the tape head and tape head frame supported thereby. Alternatively, the operation with tapes without servo tracks can be open-loop with the damping being provided by damping members disposed symmetrically on either side of the tape head frame.
