A tape cassette particularly adapted for use with a dual capstan magnetic tape deck that does not utilize pinch rollers, includes a pair of capstan actuators that respond to a central loading knob which serves to move the tape away from the capstans when the cassette is loaded or unloaded into the tape deck. In addition, the cassette includes a pair of tape guide actuators that respond to the loading knob by rotating and forcing the tape away from the magnetic head and tape guide pins of the tape deck during the loading or unloading operation. This single knob controls both the capstan actuators and the tape guide actuators. The capstans and reels are arranged such that a large angle of wrap, 165 DEG or more, around the capstans is provided in order to effectively drive the tape without the need for pinch rollers. An additional feature is the provision of a flange on one of the capstan actuators which rotates into a position when the cassette is in the play mode of operation that is effective to prevent a pin secured to the base of the tape deck from entering a cassette thereby serving as an interlock preventing loading of the cassette into the deck when the cassette is in a play mode.
