Tape drives store media by winding the tape under tension onto a hub. When the hub of the reel is accelerated or decelerated, the spirally-layered media should act as a solid disc. That is, the media should accelerate and decelerate without interlayer slip along the tangential direction of the reel. The reel hub material and dimensions must be considered to minimize the interlayer slip.
