<p>A tape-containing cartridge for accommodating an endless tape either in the form of random loops or in the form of a tape roll wound on a single reel. A tape passageway exists inside the cartridge extending from a cavity adjacent a back wall, thence between a first side wall and a first internal wall past pad means and thence between a front wall and a second internal wall past a transducer-receiving opening formed in the front wall and thence between a pinch roller and portions of the front and second side walls into the cavity. The second side wall has an opening formed at a portion thereof facing to the pinch roller for receiving an external capstan therethrough. A positional relationship between the pinch roller and the capstan is selected such that a tangential line at the contact point of the pinch roller and the capstan is directed slightly inwards of the second side wall.</p>
