Abstract: A magnetic tape transport apparatus wherein at least one capstan simultaneously drives the take-up and supply reels, and wherein tape tension is generated by a braking device allotted to each tape reel, each braking device consisting of an assembly of levers (A, B, C, and D, E, Z) and a braking cable which is wound around the axle supporting the tape reel, and by means of which the braking forces are so adjusted that it is always the axle of the supply reel which is braked, while the axle of the take-up reel runs relatively freely. In a practical embodiment, the lever assembly comprises at least three hingedly connected levers (A, B, C and D, E, Z), viz. two lateral levers and an interconnecting lever, it being possible to obtain different lever arrangements by varying the locations of the movable pivot points (G) and the fixed fulcrum points (F) FIGS. 1 to 3). The tape transport with such braking devices is suitable for all types of magnetic tape recorder, such as audio, video and data recording apparatus, and can be used with particular advantage in compact portable recorders.

Abstract: A tape transport apparatus comprising a central drive capstan and take-up and supply reels which are rotatably mounted on supports that ae movable relative to said capstan and can be urged by biasing means toward the capstan to maintain the surface engagement between the periphery of the capstan and the peripheries of the reels. To compensate for the mass moment of inertia of the movable supports and the tape reels mounted thereon, one or more counterweighting means are provided which are movably connected to the supports in such a way that the mass inertias cancel each other out.

Abstract: A strip-like recording medium, in particular a magnetic tape, is provided with at least one self-threading leader which wraps smoothly onto the periphery of a cylindrical body, the recording medium and the leader being joined to one another, over their butt joint, by a piece of splicing tape. The leader and the piece of splicing tape have a predetermined length which approximately corresponds to the circumference of the cylindrical body. A reel comprises a hub and a roll of recording medium with a leader at the beginning and/or end of the medium, the leader being attached to the medium by a piece of splicing tape of said predetermined length.

Abstract: The magnetic record/replay/erase head comprises a three unit block (5) mounted on a bearing spindle (6), the tip of which glides over a disc with a spiral shoulder (7). Rotation of the bearing spindle causes the height of the head to be modified. The front face of the head has three pick-up units (8, 9, 10)which may be used in conjunction with an array of parallel magnetic tracks so that read/write/erase may be carried out on audio or video record tracks at the same time. The ability to pick-up and record enables a video tape to have audio signals superimposed on it.

Abstract: The tape cassette consists of a flat, rectangular block shaped housing containing the magnetic tape spool, which is coupled to the drive mechanism when the cassette is engaged. The cassette consist of two sections of near enough the same size which are hinged at one end. The roll of tape will be completely enclosed when the cassette is in the closed position. The components of the housing are held together by a spring mechanism, which consists of a two pronged locking spring (14), which acts as a hinge along the narrow side (46) of the cassette. Each of the arms (47, 48) of the locking spring is connected to a part (23) of the block shaped housing. The locking spring is leaf shaped and determines the theoretical axis of rotation.
