The invention relates to a measuring cassette (1) for measuring the tape slip at the capstan (13) of a cassette player. The measuring cassette (1) is equipped with an indication disc (31), which presses resiliently against the capstan (13) and is provided with a ring of indicator segments (33, 35) which are ranged alongside one another and can be scanned by means of a measuring indicator (37) for forming a sequence of pulse signals, which is compared when the tape runs through with a sequence of pulse signals read off from the tape by means of the sound head (11). <IMAGE>
