Abstract
A leader strip is connected with a tape at one end of the tape; and the leader strip has characteristic lengthwise unit bending stiffness which is substantially greater than leader characteristic widthwise unit bending stiffness. Further, the overall width of the leader typically exceeds the overall width of the tape, and the edge portions of the leader are engageable with non-grooved inner walls of reel flanges to be frictionally retained in position between the inner walls. A magnetic tape transport is provided with two such reels between which the tape and leader are transported.
