Abstract
The present invention is an apparatus for controlled, uniform stacking of tape thereon during read/write operations in tape drives to reduce lateral tape motion during read/write operations. The invention comprises a hub and two flanges that are located on opposite sides of the hub. The flanges have surfaces facing each other extending outwardly from the hub in diverging relationship with each other. The separation between the facing surfaces of the flanges increases from a minimum at a location adjacent to the hub to a maximum at the outer circumferential edge of the flanges in a radial direction extending outwardly from the axis of rotation. Further, the separation between the facing surfaces also increases from a minimum to a maximum along any path of equal distance around the axis of rotation, the location of minimum separation is generally opposite to the location of maximum separation. The minimum separation is such with respect to the width of the tape being spooled thereon as to be effective to ensuring uniform stacking of the tape around the hub as the tape is spooled.
