Abstract
Method and apparatus for protecting and storing media, such as magnetic storage discs. A protective cover is formed by a front side, a back side and a mechanism for engaging a storage container. The front side can be connected to the back side by a base that promotes the separation of the sides and their closure towards one another, or includes a recess conforming to the object to be protected, with at least one side having a detent for promoting the retention of the object, such as a rectangular jacket with a movable shutter for a magnetic storage disc. The recess can include a shutter lock. The protective cover is insertable into a storage tray which retains the protective cover by, for example, hingeable extensions of the tray which are folded against sides of the tray when the cover is to be inserted, and the cover is retained unless it is moved to a substantially vertical position which permits withdrawal.
