The cassette tape recorder for the four common types of cassettes according to German Industrial Standards DIN 32 715 T, 32 715 W, and the so-called micro-cassette as well as the mini-M-cassette comprises three sound head carriers (10, 20, 30) adapted to be moved selectively into operating position. Furthermore, the spacing between winding shafts (2,2') is adjustable by a movable cam disc (17). This adjustment is taken care of by cam disc engaging fixtures (23, 33) at the movable sound head carriers (20 and 30, respectively) and by a spring (18) holding the cam disc (17) in an inoperative position against a stop. Likewise provided are adjustable winding heads (3,3') causing different engagement members (4,6) to become effective for the winding drive, the adjustment of the winding heads (3,3') also being effected upon moving of the sound head carriers (10,20,30). Scanning members serve to scan a geometric dimension of the cassette and based on that scanning the spacing of the winding shafts (2,2'), the position of one of the sound heads (14,35,60) and, if desired, adjustment of the winding heads (3,3') and their engagement members (4,6) are determined.
