    Abstract: In an extrusion coater having at least two coating slots (8, 8'), the central line between the coating slots is arranged perpendicular to the plane of the substrate (1) and the terminating edge (15) of the separator (16) between the two coating slots is a downward-sloping surface. Opposite the extruder orifice and behind the substrate is the edge (5) of a magnet (2) which draws the magnetizable layers out of the coater outlet orifice (3), the edge (5) being arranged at the height of the common outlet orifice of the coating slots (8, 8'). By means of this arrangement, a uniform coating is achieved even in the case of very thin double layers and even at high coating speeds.

    Abstract: The invention relates to a magnetic recording medium comprising a) a layer carrier, b) at least one lower non-magnetic layer which is applied to said carrier and comprises at least one binding agent, and c) an upper magnetic layer which is applied to the lower layer, and which, dispersed in at least one binding agent, comprises at least one magnetic metal pigment or metal alloy pigment having a passivating envelope. Said recording medium is characterised in that the upper magnetic layer has a maximum dry thickness of 300 nm; the magnetic metal pigment or metal alloy pigment has a maximum length I of 90 nm; and the length I' of the metal core, the length I of the pigment, and the shortest recording wavelength lambda for the magnetic recording on the medium follow the relation: I'/I#1-18/ lambda . At least the binding agent of the magnetic layer contains both chlorine and epoxy groups, or is free of chloride.

    Abstract: Roll made of media in one of strip or tape form and process for producing the roll, the roll including a hub with a data recording medium in one of strip or tape form wound thereon, the data recording medium having a tape end fastened on a roll of the data recording medium by way of a printed adhesive strip. A sealing element of the roll is formed by an adhesive strip having an adhesive underside. The adhesive strip overlaps the tape end with its one end by a first length and overlaps a label strip with its other end by a second length. The adhesive strip is adhesively attached to the upper side of the label strip. The adhesive strip is adhesively bonded to the outer circumference of the roll between two overlapping regions in a region with a third length. The label strip is provided on its upper side with an identification coding.

    Abstract: A method of and apparatus for producing a transparent film or a transparent layer with a surface structure at least on one side and, on the other side, in register with said surface structure, a structural or 2-dimensional pattern, operate with at least two rotating rollers and layer application between them and curing of a structural layer. By means of a third rotating application roller, a further layer can be applied in register to the rear side of the structural layer and can be cured. The rollers and roller nips can be set very accurately by suitable devices. The rotation of all the rollers is controlled by a master drive.

    Abstract: Magnetic-tape cartridge includes a substantially rectangular housing. At least one tape reel is rotatably mounted in the housing. The at least one tape reel is configured to receive wound magnetic tape. A first part is axially movably mounted in a center of the at least one tape reel. A second part is non-rotatably mounted and axially movably mounted to a housing wall of the cartridge via a spring. The first part is movable between a resting position and an operating position in which the first part moves the second part against the biasing force of the spring. The second part is movable between a first position, thereby preventing the at least one tape reel from rotating, to a second position thereby allowing rotation of the at least one tape reel
