摘要： The invention relates to a hub for magnetic tape cassettes, especially compact cassettes, and to magnetic tape cassettes possessing such hubs. In a first embodiment, spring means are provided on the inner periphery of the hub and exert radial pressures on the drive spindle, the spring means consisting, for example, of sprung teeth. In a further embodiment, the teeth have a spring rate of from about 1 P/mm to 40 P/mm. In another embodiment, the hub consists of an inner part and an outer part which can be coupled to one another and between which there is some play after coupling. A large number of specific examples of hubs are given to show possible shapes and arrangements of the teeth, and to show the types of material that can be used. In an advantageous embodiment, the inner part of the two-part hub can also be made a part of the drive spindle on the recorder, which inner part can be coupled with the outer part when the drive spindle enters the cassette.
