ABSTRACT:
A high torsional stiffness, low axial deflection stiffness, low angular deflection stiffness and low radial deflection stiffness tape drive coupling apparatus includes a base adapted for attachment to a drive motor and a driver engageable with a cassette reel. First and second pairs of parallel flexible rolling tubes are positioned between the base and driver, and the two pairs are disposed orthogonally with respect to each other. In this configuration, the driver is movable axially and angularly with respect to the base by compression and expansion of the flexible tubes. The driver is movable radially with respect to the drive axis by rolling of at least one of the pairs of tubes. The driver is relatively torsionally rigid with respect to the base to facilitate rotational driving engagement of the cassette reel when there exists axial, radial or angular misalignment between the driver and cassette reel.
