Abstract
A reel particularly designed for carrying magnetic tape, such as that used in reel to reel tape recorders, has a hub having at the axial extremities thereof discs for retaining the tape on the hub. The discs are provided with a plurality of holes disposed at various radial distances from the axis of the reel. Each hole in one disc is disposed in aligned relationship with a corresponding hole in the second disc. The axes of the aligned holes in the two discs are disposed in generally parallel relationship to the axis of the reel. Pins are selectively positioned in the aligned holes to limit unwinding of the tape carried on the reel.
