  • Patent number: 7484681
    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: 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: 6568618
    Abstract: The half-inch tape drive comprises a novel takeup reel, tape deck, PC board packaging, loading mechanism, and housing. The takeup reel comprises a pair of segmented flanges that define a first and second tape containment section. The tape deck is approximately half the height of a conventional tape deck and includes reinforcing ribs to provide structural rigidity and maintain alignment of the moving components of the tape drive during operation. The loading mechanism comprises a horizontally mounted load motor that employs a worm gear to engage a simplified gear train. The printed circuit board is segmented into multiple sections that are mounted in various locations on the tape drive to maximize spatial efficiencies and reduce the overall height of the tape drive. The tape drive housing provides a protective exterior for the tape drive components and provides the structure for mounting the present tape drive in a single drive bay of a computer housing.
