Abstract: In a cassette for a magnetic tape, which has a housing with a housing wall formed with an access opening for a magnetic head, and a tape-pressure device including a pressure-pad support and, arranged thereon, a pressure pad having an elastic base of a foam material, the foam material has open pores at the surface region which faces the magnetic tape during pressing and a polytetrafluoroethylene layer is anchored in the open pores.

Abstract: Method of manufacturing a magnetic-tape cassette having at least one antifriction foil separated from an antifriction-foil stack, magnetic-tape cassette manufactured by such a method, antifriction-foil stack for use in such a method of manufacturing such a magnetic-tape cassette, and method of manufacturing such an antifriction-foil stack.In a method of manufacturing a magnetic-tape cassette (23.sub.1, 23.sub.2), in which method an antifriction foil (8.sub.1, 8.sub.2) is inserted into at least one housing section (10) of the housing (11) of the magnetic-tape cassette (23.sub.1, 23.sub.2), which antifriction foil is separated from an antifriction-foil stack (9) and has at least two raised portions (13.sub.1, 14.sub.1, 15.sub.1, 16.sub.1 ; 13.sub.2, 14.sub.2, 15.sub.2, 16.sub.2, . . . 13.sub.2n, 14.sub.2n, 15.sub.2n, 16.sub.2n) which are spaced at a distance (a.sub.1, b.sub.1, a.sub.2, b.sub.2) from one another, the antifriction foil (8.sub.1, 8.sub.2, . . . 8.sub.

Abstract: A magnetic tape having an elongate pressure-member support for supporting a pressure member and an elongate tape-guide-element support for supporting two tape guide elements. Two abutment parts are arranged at the location of side portions of the pressure-member support and the tape-guide-element support and take up the forces exerted by the side portions when the magnetic head cooperates with the pressure member and the tape-guide elements. The pressure-member support has at least one opening in each of the two areas of its side portions which face the abutment parts. The abutment parts and/or the tape-guide-element support have projections at parts of the side portions which face the abutment parts projecting towards the facing part of said two parts which projections are arranged to correspond to the openings in the pressure-member support.

Abstract: In a cassette (1) comprising a pressure-member support (58) arranged adjacent a side wail (8) to hold an elastic pressure member (56) by means of which a magnetic tape (2) can be pressed against a magnetic head which can be introduced into the cassette (1), and comprising a tape-guide-element support (69) arranged between the side wail (8) and the pressure-member support (58) and having two tape-guide elements (67, 68) arranged mirror-symmetrically relative to the pressure member (56), the pressure-member support (58) comprises two stepped portions (79, 80) such that its central portion (57) is offset relative to its two side portions (59, 60) towards the tape-guide-element support (69) adjacent the pressure-member support (58), and the central portion (57) of the pressure-member support (58) is supported on the tape-guide-element support (69) under the influence of a pretension.

Abstract: A cassette (1) for a record carrier (10) is provided with a sliding cover (2) for covering at least one opening (13, 14, 15, 16, 17, 18, 19, 20, 21) in the cassette housing (3), which cover has at least one plate-shaped flange (28) which extends parallel to a main wall (5) of the cassette housing (3), hold-down means (41) overlying its edge zone (31), which extends parallel to the direction of movement (22) of the sliding cover (2) and has a given length (L), in order to hold down the flange (28). Suitably, the hold-down means (41) comprise at least two hold-down members (50, 51) whose dimension (A) parallel to the direction of movement (22) of the sliding cover (2) is only a fraction of the length (L) of the edge zone (31) of the flange (28) of the sliding cover (2), over which edge zone said hold-down members engage.

Abstract: A cassette comprises a housing which accommodates a magnetic tape partly wound on two reel hubs. A main wall of the housing has two openings which are coaxial with the reel hubs to allow the passage of reel spindles of a drive apparatus. The cassette further comprises a slide cover for covering the openings, which slide cover comprises blocking members which can cooperate with the reel hubs to inhibit their rotation. For this purpose the wall with openings has diametrically opposed recesses or cut-outs to allow the blocking members to engage with inner teeth provided in the reel hubs.

Abstract: A rectangular holder (1) has two main walls (2,3) and three side walls (4,5,6) and is open at a fourth side (7) and comprises a clamping member (11) for clamping a cassette in the holder (1), which clamping member is situated at the location of at least one side (4) adjacent the open side and is made of an elastic material. The clamping member has an internal cavity substantially at the location which projects into the holder interior.
