    Abstract: The generation of tape tension, based on the capacity for elastic flow of elastomeric incompressible layers, in a tape transport apparatus employing at least one capstan in contact with supply and take-up reels of tape is accomplished by producing a higher compressive force at the point of contact between the take-up reel and the resiliently deformable peripheral portion of the capstan than at the point of contact between the supply reel and the capstan. The difference in compressive forces is brought about by an additional force which is produced by means of a drivable rotating body and is transmitted to the tape reel carriers by means of a cable which is guided over this rotating body.

    Abstract: A tape guide, especially a guide for thin magnetic tapes which are subjected to strong acceleration forces in the longitudinal direction, and a tape transport apparatus with a central capstan, comprising such a tape guide. The tape guide includes one or two rotatable, but fixedly arranged guide rollers having flanges arranged around part of the periphery thereof, which flanges each have an ingress and an egress chamfer for the tape. When one guide roller is used, the magnetic head is positioned between a tape reel and the guide roller and, when two guide rollers are used, it is positioned between the said two rollers, the magnetic head bearing against the unsupported span of tape in each case. The tape guide may be provided with means for producing cushions of air for stabilizing the roller as it rotates.

    Abstract: The cartridge arrangement of the present invention enables recording and/or playback apparatus to be used with cartridges of various sizes, the cartridges being provided with releasable locking means and, after the release of such means, being able to be opened to permit the tape roll(s) to be rotated on the recording and/or playback apparatus. The cartridge arrangement is applicable to every type of recording medium in tape or strip form in systems employing cartridges in which there is a need for using cartridges of various sizes, especially in the case of the recording and playback of magnetic signals.

    Abstract: Magnetic recording media in which, following application of the magnetic dispersion to a web of tape base material, the magnetic particles are oriented in a preferred direction and the magnetic dispersion is dried to fix the magnetic particles in their oriented position. To assist the orienting action of the orientation magnet, a blanket is located between the latter and the coating device, which blanket is caused to make sliding contact with the applied magnetic layer.
