  • Patent number: 9171566
    Abstract: Embodiments include systems and methods for buckling in a loader assembly of a tape storage drive. Some implementations translate driving forces of an elevator of the loader assembly into driving forces that act on a pusher plate of a buckling mechanism in both buckling and unbuckling directions. For example, a plate interface can couple the pusher plate with the elevator in a manner that translates rotational motion of the elevator's drive gear into a lateral driving force that drives the pusher plate between its home and buckling positions. Certain implementations also include a home holding mechanism for removably securing the pusher plate in the home position when the elevator is in its unloaded position.

    Abstract: A data storage cartridge that uses a tape buckling mechanism to connect a reel of tape to a tape drive is enhanced with a buckle reinforcement feature on the cartridge door. The reinforcement feature fits between two buckle clips of the buckling mechanism, and provides reinforcing support to the buckle clips. The reinforcement feature supports the clips and thereby prevents bending and misalignment of the clips. If the clips do become bent or misaligned, the reinforcement feature prevents the door from closing completely. A user will clearly see that damage has occurred, and the user will be less likely to damage the drive by attempting to use the cartridge. Furthermore, the reinforcement feature can be wedge-shaped, so that the user may straighten the bent clips by applying additional force to the door.

  • Publication number: 20080164358
    Abstract: It is an object of the present invention to provide a magnetic recording/reproducing apparatus and a tape threading method thereof capable of preventing cut or slip of a leader tape, and capable of effectively preventing the fixing force from being deteriorated due to variation with time. In a magnetic recording/reproducing apparatus, an end of a tape accommodated in a tape cassette 2 has a coupling element 8, and the coupling element 8 is pulled out by a tape-pulling-out element 40 and the tape is taken up around a drive reel 20. The magnetic recording/reproducing apparatus comprises a leader tape 41 having one end connected to a drive shaft 24 of the drive reel 20 and the other end connected to the tape-pulling-out element 40, a reel hub 21 which is located on an outer periphery of the drive shaft 24 and which takes up the tape around an outer peripheral surface of the reel hub 21, and a lock member 70 which connects the drive shaft 24 and the reel hub 21 with each other.

  • Publication number: 20080135663
    Abstract: In one example, a tape drive system including a buckler system having a hook member is provided. The tape drive system includes a take-up leader and a buckler, the buckler for selectively retaining the drive leader, the buckler comprising a hook member for extending through an aperture of the take-up leader, the aperture having an area substantially equal to a cross-sectional area of a proximate portion of the hook member. In another example, a length of a proximate portion of the hook member along a longitudinal direction of the take-up leader is substantially equal to the longitudinal length of the aperture in the take-up leader.

  • Patent number: 7380738
    Abstract: The present invention provides a magnetic tape device capable of reliably securing a leader tape to a tape pull-out member with a simple structure. The tape pull-out member comprises a through hole which is extended along a direction substantially perpendicular to the pull-out direction of the leader tape, and a first shaft and a second shaft which are disposed above and below the through hole and along a direction perpendicular to the pull-out direction of the leader tape. The leader tape is folded at its end portion which is to be connected to the tape pull-out member, to thereby form the folded portion of the leader tape, and this folded portion is turned to form an opening at its top curved portion so as to allow the first shaft to pass through the opening, and is then so hung on the second shaft as to turn around the second shaft.

  • Patent number: 7372668
    Abstract: A brush driving mechanism, which drives a cleaning brush from a retracted position to an operation position opposed to a magnetic head, has a main arm having a tip coupled to the cleaning brush through a shaft. A chassis has a chassis slit, in which the shaft is inserted, for allowing to move the cleaning brush from the retracted position to the operation position by operating the main arm. The chassis slit has a tip portion stops the shaft when the cleaning brush is put into the operation position to position the cleaning brush with respect to the magnetic head.

  • Patent number: 7344100
    Abstract: A driving mechanism, which drives a pull-out assembly up to an interior of a reel hub of a take-up reel, has a shaft which is inserted in a through hole bored in a grabber with a clearance. A shutter fixes the pull-out assembly in a receiving portion at a predetermined position on receiving the pull-out assembly in the receiving portion. A positioning member positions the shaft with a center of the shaft substantially coincided with a central axis of the take-up reel and with the clearance held between the shaft and an inner wall of the through hole when the pull-out assembly is received in the receiving portion.

  • Patent number: 7338002
    Abstract: A dual hub reel for a tape drive comprises an inner hub operatively connectable to a motor and a flexible leader connected at a first to the inner hub so as to be wound on to the inner hub when driven, to rotate by the motor. An outer hub is disposed about the inner hub and has an opening through which the flexible leader extends. The outer hub is arranged on the inner hub and is selectively freely rotatable about the inner hub or locked against the inner hub to rotate with the inner hub. A locking element is responsive to pressure supplied by a tape wrap to press against the inner hub and lock the outer hub to the inner hub by interaction of an engagement surface against the inner hub.
