ABSTRACT:
A cleaning apparatus for optical or magneto-optical storage disks includes a first rectangular part having four lateral edges and a raised interior, the interior having at least three troughs for holding utensils for cleaning the optical or magneto-optical storage disks; a second rectangular part having four lateral edges, an interior which is shaped complementary to the interior of the first rectangular part, and a border which runs completely along its four lateral edges for enclosing a disk cassette of a magneto-optical or optical storage disk inserted for cleaning; and a back strap for connecting the two parts to each other such that the two parts can be folded together, similarly to a book, and locked along their lateral edges. The second part further includes a disk bearing which, when the storage disk is inserted, raises the storage disk inside the disk cassette to such an extent that the storage disk is rotatable without friction. A locking device is provided on the interior of the second part for keeping a shutter of the disk cassette open. The interiors of the first and second parts, together with the troughs, the edge beads, the locking device, the disk bearing, and the border are deep-drawn from plastics film.
