Abstract: The invention relates to an apparatus for the storage and/or reproduction of information on/from an information carrier accommodated in a cartridge. The apparatus comprises a motorized loader for the motorized loading of a cartridge. The apparatus has a mechanism by means of which the cartridge can be pulled into the apparatus with a first transmission ratio and is subsequently moved into an operational position with a second transmission ratio. The mechanism is based on the fact that the motorized loading mechanism comprises an element having two contact surfaces which are disposed at an angle relative to one another.

Abstract: A magnetic cassette recorder comprises a magnetic head 19 which can be translated in directions 21 and 23 between an operating position, in which the head cooperates with a magnetic tape in an inserted cassette 3, and a withdrawn position, in which the head is clear of an inserted cassette. In the withdrawn position the head can be pivoted about a pivotal axis 25 between a first angular position and a second angular position. The head is electrically connected to stationary parts of the recorder by means of a flat flexible multiple electrical conductor 27, such as a foil carrying printed electrical conductor tracks or a flat cable. The conductor is arranged as a cylindrical spiral about the pivotal axis 25 and its end 55 which is remote from the head is connected directly to stationary parts of the recorder, so that translations of the head in the axial direction result in the spiral being extended/compressed and pivotal movements of the head result in the spiral being coiled/uncoiled.

Abstract: The invention relates to an apparatus for the storage and/or reproduction of information on/from an information carrier accommodated in a cartridge. The apparatus comprises a motorized loader for the motorized loading of a cartridge. The apparatus has a mechanism by which the cartridge can be removed from the apparatus in the case of faults.

Abstract: The system in accordance with the invention comprises a cassette (101) and an apparatus (102). The cassette (101) has a housing (110) which accommodates two reel hubs (121 and 122) and an optical tape (140). The optical tape (140) extends past a transparent optical window (118) which is accessible from one side (113a) of the cassette. The reel hubs (121 and 122) are connected to comparatively large winding wheels (131 and 132, respectively). The wheel surfaces (131a and 132a) of the winding wheels (131 and 132) are engageable with and drivable by driving surfaces (181a and 182a, respectively) of the apparatus (102) via openings (113b and 113c). The driving surfaces (181a and 182a) form parts of drive wheels (181 and 182) mounted on shafts of the electric motors (183 and 184). The apparatus (102) further comprises an optical head (172) for writing and/or reading information on/from the optical tape (140) via the optical window (118).

Abstract: A magnetic tape apparatus having a magnetic head, reel drive spindles for driving the reels of a magnetic tape cassette and a pressure roller-capstan combination for driving the tape within the cassette. The apparatus includes an actuating member with urging projections for sliding a slidable cover on a magnetic tape cassette of a first type, having a first thickness between its main walls, when the cassette is inserted into the apparatus. A sensor on the actuating means senses the insertion of a cassette of a second type, having a thickness between its main walls greater than the thickness of the first type of cassette, for moving the actuating member to a position which permits the second type of cassette to be fully inserted in the apparatus and cooperate with the reel drive spindles, the pressure-roller-capstan arrangement and the magnetic head.

Abstract: A cassette comprises a housing provided with magnetic tape and having two pressure-roller openings and one magnetic-head opening. The cassette also comprises a sliding cover for covering the openings in the housing, which sliding cover is movable between a closed position and an open position. The thickness (t2) of the cassette is 9.6 millimeters. This results in a more rigid construction of the sliding cover.

Abstract: A system is provided which records reproduces signals on/from a magnetic tape in a cassette in longitudinal tracks in two track patterns in two adjacent tape zones which are inscribed/read in opposite directions. The cassettes are non-reversible and comprise one imperforate main wall. Without exception the associated apparatuses comprise, as a standard feature, recording/reproducing signals in the two opposite directions without reversal of the cassette. The system may be constructed as a two-standard system suitable for use with both reversible and non-reversible cassettes in conformity with non-compatible standards on two-standard apparatuses.

Abstract: An apparatus (1) has a magnetic-head unit (17) with a housing (18) in which a magnetic head (47) is situated. The magnetic head (47) has a head face (49) in which a gap end of a transducing gap (51) extends and a first mounting surface (107) perpendicular to a gap plane (59) through the transducing gap (51). The magnetic-head unit (17) has a front section (29) of which tape guides (31, 33) form part and which is provided with a second mounting surface (75), which is positioned relative to the first mounting surface (107) of the magnetic head (47). This results in an accurately defined position of the magnetic head (47) relative to the tape guides (31, 33).

At one side the holder has a first opening, which gives access to the first compartment, and a second opening, which gives access to the second compartment. The holder further comprises a cover arrangement with a first cover, which in the closed position closes the first opening, and a second cover, which in a closed position closes the second opening and extends both over the first opening and the second opening. The first cover is connected to the partition via a first hinge and the second cover is connected to the first cover via a second hinge.

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 helical scan magnetic-tape apparatus (1) including at least three tape guides (2, 25, 27, 28, 29, 30, 32, 33), including a magnetic-head unit (2). The apparatus (1) co-operates with a magnetic tape (8) wound on reels (9, 10) in a cassette (44). The tape-transport path in the apparatus includes at least three path sections (35, 36, 37) in which the tape (8) is twisted through a specific angle to correct for differences in level and inclination arising as a result of the helical path of the magnetic tape (8) around the magnetic-head unit (2).
