Abstract
A continuous loop tape cartridge including a housing in which an endless tape is wound as a coil on a main hub disposed within the housing. During operation the tape is withdrawn from the center of the coil and wound onto the outside of the coil. A rewind hub is coaxially mounted with respect to the main hub and includes an accessible portion adapted to be driven to rewind the tape from the outer convolution of the coil onto the rewind hub.
