TONBANDKASSETTE MIT VIER SPULEN

A magnetic tape cartridge in which two pairs of coaxial reels are rotatable about spaced parallel axes, each reel being aligned in planes perpendicular to said axes with one reel in the other reel pair. The reels in one coaxial pair are independently rotatable while the reels of the other pair are rotatable together. And, a first length of magnetic tape extends between two of the aligned reels and is convolutely wound about their axes in the same direction while a second length of magnetic tape extends between the other two aligned reels and is convolutely wound about their axes in opposite direction, the lengths of tape being wound on the independently rotatable reel pair in the same direction about their common axis.
