ABSTRACT:
In a magnetic tape cassette, the cassette housing is divided between the two roll cores by an elongated isolator extending from the working edge of the cassette to the opposite edge thereof to prevent tape loops formed in the housing adjacent one roll core due to a slack tape condition from propagating to the other core where they could become snagged by tape winding onto that other core thereby causing a tape jam or break. One end of the isolator is pivotally mounted to the housing so that the isolator can swing freely between the two roll cores as the amount of tape wound on the two cores varies and, during operation of the cassette, the isolator does not exert any appreciable drag on the rotating tape rolls.
