Abstract
Abstract A miniaturized tape cartridge is provided and which is designed to fit within a cartridge container of dimension allowing the container/cartridge assembly to be inserted into and played in a conventional-type eight-track player machine. The container is designed and provides for the insertion of the tape cartridge within either end of the container, and either end of the loaded container may be inserted into the eight-track playing machine. The container includes a pair of pinch wheels, one at each end thereof, whereas the pinch wheel of the tape cartridge is effectively eliminated. Within the tape cartridge is a continuous loop of magnetic tape. The tape cartridge is so constructed and arranged whereby it will record and play the same amount of material as the conventional eight-track tape musical album.
