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.
