Abstract: An enclosure system for storage of electrostatically active, planar articles such as spark-discharge recording media. The enclosure includes a container portion, which defines a cavity for containing the articles and is conductive on all surfaces; and a nonconductive lid that fits over the container. In one embodiment, the enclosure cooperates with a set of interleaving sheets that a user places between the articles, and which make contact both with charged surfaces of the individual articles and the conductive interior of the container. In another embodiment, the interleaving sheets are integral with the article itself, thereby ensuring separation of each article from the one underneath by a layer capable of conveying electrostatic charge to the container.
