Abstract: In a tape cassette, particularly a video tape cassette, equalization of electrostatic charges between the two faces of the tape is effected by a connector element or connector elements electrically connecting at least one of two electrically conducting guide elements contacting the front of the tape and provided on the two sides, respectively, of the cassette with at least the associated one of two electrically conducting tape deflecting elements provided in the two respective front corners of the tape cassette. In this manner sticking of the tape to the deflecting elements due to electrostatic attraction therebetween and also the build-up of electrostatic charges along the tape path parallel to the front of the cassette housing due to the transporting of such charges from the deflecting elements as a result of the tape travel, are counteracted.

Abstract: A process and apparatus for producing magnetic discs in which the preferred direction of orientation of the anisotropic magnetic particles, contained in an organic binder system, is tangential to the circumference of the disc. Orientation is effected, prior to solidification of the magnetic layer, by the action of a magnetic field which is formed in the plane of symmetry between at least two pairs of magnetic poles, the poles of each pair being of the same polarity and opposite each other. One pair of poles flares out in cross section toward the plane of symmetry between the pairs of poles, whereas the other pair or pairs of poles of opposite polarity, when viewed in cross section, taper toward the said plane of symmetry to a point, the distance between the poles of such pair(s) being greater than that between the flared poles, and the plane of symmetry of the pairs of poles being in the plane of the disc. Using this process and apparatus, magnetic discs with a non-magnetic metallic base are obtained, in which the anisotropic magnetic particles in the layer of fluid binder applied to the base are oriented tangentially to the circumference of the disc during spin-coating.
