摘要： A pressure device for recording media in tape form, in particular magnetic tapes, has at least one pressure element and comprises a support element. When the device is actuated by the head coming to bear, a deflection of the device takes place, and a pressing against the recording medium is effected automatically by at least one extension of the support element, this pressing ending automatically when the head is no longer in bearing contact. The bearing pressure may take place directly on the tape rear side or tape front side, or else indirectly on the tape front side or the tape rear side or both sides simultaneously. Pressing and/or antifriction and/or cleaning elements may also be arranged, at least partially, fixed in place with respect to the tape. The invention can be used in the case of all cassettes, film and magnetic-tape systems.
