A tape cassette of a relatively small size for use in portable tape devices and the like. The cassette is formed out of two displaceable sections containing respective winding spools for the tape wherein in the sections move from a first position in which the cassette is relatively small to a second or expanded position wherein the cassette can be used in a larger tape device. A receiving container is provided adapted to receive the tape cassette to provide an outer dimension of a larger size, such as that utilizable in a standard video player/recorder.
