Abstract
A continuous loop tape cassette with a rotating tape coil carried by a flanged, reverse e-shaped hub in fixed radial angular relation to the base of the cassette. A tape receiving arc portion of the hub has a radius sufficiently great relative to the spring modulus of the tape to prevent binding. The arc portion is undercut to contain the tape.
