Abstract: A guide for guiding a magnetic data storage tape has a curved support portion for supporting a major tape surface and at least one flange adjoining the support portion. At least in a region of transition between the support portion and the at least one flange, the guide has an under coating of a diamond like carbon material, tungsten carbide, or similarly wear resistant material, and a surface coating having lower surface tension than the under coating. A tape guide apparatus and a method of making a tape guide are also disclosed.

Abstract: In a storage device (1) and in a storage container (3) which can be loaded into the storage device (1), the storage device (1) has holder means (46) for holding a storage container (3) which are guided so as to be movable between an loading position and an operating position and which are movable out their loading position in a first direction of movement (74) and which are movable into their operating position in a second direction of movement (75) which is oriented transversely to the first direction of movement (74), and the storage container (3) has container-mounted positioning means (15) and the storage device (1) has device-mounted positioning means (156), the cassette-mounted positioning means (15) and the device-mounted positioning means (156) are constructed and arranged in such a manner that during a movement of the holder means (46) from their loading position into their operating position the storage container (3) can be positioned with respect to the device-mounted storage processing means alrea

Abstract: A recording and/or reproducing apparatus (1) which accepts two different sizes of magnetic-tape cassettes (15, 16) each having two juxtaposed reels (21, 22, 23, 24) comprises four drive devices (25, 26, 27, 28) mounted stationarily in the apparatus and each comprising a reel spindle (31, 32, 39, 40) and a reel disc (33, 34, 41, 42). Both the reel spindles (31, 32, 39, 40) and the reel discs (33, 34, 41, 42) are axially movable and, when a magnetic-tape cassette (15, 16) is loaded into the apparatus (1) in its operating position, the reel spindles (39, 40, 31, 32) and the reel discs (41, 42, 33, 34) which are not adapted to enter into driving engagement with the inserted magnetic-tape cassette (15, 16) are moved into an area situated outside the area occupied by the inserted magnetic-tape cassette (15, 16).

Abstract: A recording and/or reproducing apparatus which accepts two different sizes of magnetic-tape cassettes each having two juxtaposed reels comprises four drive means mounted stationarily in the apparatus and each comprising a reel spindle and a reel disc. Both the reel spindles and the reel discs are axially movable and, when a magnetic-tape cassette is loaded into the apparatus this cassette is detected by means of the reel spindles which are not adapted to enter into driving engagement with this cassette. The reel spindles and the reel discs which are not adapted to enter into driving engagement with this cassette are moved into an area situated outside the area occupied by the inserted magnetic-tape cassette by the cassette housing.

Abstract: To drive the magnetic tape (2), a magnetic-tape apparatus (1) has a drive arrangement (18) comprising at least one brake disc (37, 38) which is rotatable in opposite directions of rotation (30, 33, 27, 36) and which can be braked by a block-brake device (39, 40). The block-brake device (39, 40) includes a brake block (41, 42) arranged on a first level (43, 44), which first lever is pivotally connected to a second lever (47, 48) which is pivotable about a pivot (49, 50). A coupling is arranged between the two levers (43, 47, 44, 48) to provide a positive coupling during braking in one direction of rotation (33, 27) of the brake disc (37, 38), and the two levers are interconnected via a spring to provide a non-positive coupling during braking in the other direction of rotation (30, 36) of the brake disc (37, 38). A single spring rod (61, 62) performs the coupling and the spring functions and has both ends (63, 64, 65, 66) connected to the two levers (43, 47, 44, 48).

Abstract: In a recording and/or reproducing apparatus (1) with a housing (7) and with a chassis (12) connected to a housing part (16), the chassis is connected to the housing part (16) via three connecting arrangements (13, 14, 15). Each connecting arrangement (13, 14, 15) has a supporting part (18, 19, 20) firmly connected to the housing part (16) and having a convex spherical supporting surface (21, 22, 23) facing the chassis (12), and a counterpart (24, 25, 26) connected to the chassis (12) and having a rotationally symmetrical, preferably like-wise spherical mating surface (27, 28, 29) which widens continuously towards the housing part (16).

Abstract: A capstan drive tape recorder having a pressure roller on an arm which is pivotable to hold the tape against the capstan. To move the arm between the operating and a rest position, the arm is connected by a spring to a lever, the arm and lever being pivotable about the same axis. An actuating device moves the lever to bring the pressure roller into engagement with a tape against the capstan. In moving the arm, the lever is first pivoted about one axis, and then about a second axis so that the mechanical advantage of the lever is changed between a ratio which moves the roller a considerable distance, and a ratio which biases the roller against the capstan.
