  • Shear clamping method
    Patent number: 5551139
    Abstract: A leader block is provided for connection to a free end of storage tape media. The leader block includes a main body and a clamp member. The main body and clamp member define a space for receiving the free end of the storage tape media. A punch member is joined to the clamp member. The main body, the clamp member and the punch member are parts of a single, integral device that is preferably made by molding. After the storage tape media is inserted into the receiving space between the main body and the clamp member, the clamp member is caused to move relative to the main body by applying sufficient, predetermined shear forces. The punch member is also caused to move relative to the clamp member. The storage tape media is sandwiched between the main body and the clamp member using forces provided by the punch member and clamping forces caused by the main body and the clamp member.

  • Take-up reel assembly having Radii at discontinuities to minimize tape impressions
    Patent number: 5431356
    Abstract: A take-up reel assembly for use with a single-reel tape cartridge in a cartridge-based tape transport includes a take-up reel and a leader block. The take-up reel includes an annular hub having an axis of rotation and a radial surface adapted to have the tape wound thereon. A radial slot in the hub extends from the radial surface towards the axis of rotation. The leader block is configured for attachment to a free end of a length of tape in the tape cartridge. The leader block has a shape substantially the same as the shape of the radial slot in the hub of the take-up reel.
