ABSTRACT:
A cartridge including a cylindrical hub fixed on a housing, which hub has a central opening and a slot extending axially across the full width of the hub and communicating with the central opening, and an endless length of magnetic tape having a major portion wrapped about the hub to form a coil and a minor portion extending from the innermost wrap of the coil, through the slot and around the side surface of the coil to the outermost wrap of the coil. Means on the housing define a tape path for the minor tape portion at the access openings which afford engagement of the tape by the heads and drive mechanism of a playback machine, and a spring biased moveable guide pin guides the minor tape portion between the access openings and the outermost wrap of the coil, and provides a low tension in the outermost wrap of the coil which in turn produces a relatively high generally unifrom tension in the tape crossing the tape heads to hold it in engagement therewith without the use of pressure pads.
