Abstract: A protective jacket, in particular for recording media, preferably magnetic films, is provided with at least one stiffened region in the immediate vicinity of the read/write area, thus permitting more thorough cleaning of the recording medium and smoother running of the latter. Stiffened region(s) can be produced economically by printing on strips of ink.

Abstract: A protective jacket for recording media, in particular flexible recording media, is provided with a network or grid of conductor paths (6) to counteract electric charges, Advantageously, the jacket blank (1) is coated uniformly, in particular on both sides, with linear conductor paths (6). The protective jacket can be used for storing any recording media outside a recording/playback apparatus, or for operating any recording media inside such an apparatus. It is advantageous if, in the areas in which the blank (1) is welded to form a partially or completely closed jacket after folding, a conductor path grid or network is provided so that areas which are free of the conductive layer and are of prescribed dimensions are available between the conductor paths, such areas being necessary for welding.

Abstract: A film web, from which cut-to-size pieces (1) for the jackets are punched out, is provided by means of a printing process with an electrically conductive coating (6) which, at the locations (5) at which the cut-to-size piece is welded after folding to form a closed jacket, runs into a line gridwork (7), so that between the lines coating-free locations are available, required for the welding.

Abstract: A recording medium possessing an envelope has at least one identification part which is mounted so that its position can be altered but it cannot be accidentally lost, and which is symmetrical about at least one axis, in particular a middle axis, and is associated with at least one wall of the envelope. To permit error-free assembly/handling, the identification part advantageously has a shape which permits at least two equivalent mounted positions on the envelope.
