An enclosure for optical disks comprising: a rectangular top portion comprising a top wall, a pair of opposite depending side walls and a depending end wall; a rectangular bottom portion, including a bottom wall, sized to align with the bottom edges of the depending side walls and end wall of the top portion; welds securing the top and bottom portions at spaced apart locations along their periphery with the top and bottom walls in generally parallel, spaced relation for forming a box-like structure defining a cavity therewithin, the box-like structure having an access opening along its end opposite the end wall for permitting the insertion and removal therethrough of optical disks into and from the cavity; rigid projections projecting into the cavity from opposite side walls for reducing the side-to-side dimension of the cavity to less than the diamerter of the disk at a location along the side walls, the location positioned between the access opening and the point along each side wall corresponding to the diameter of the disk when fully received within the cavity, whereby the spaced apart welds allow the side-to-side dimension of the cavity to temporarily enlarge under the influence of the force exerted by the disk on the rigid projections, the side-to-side dimension of the cavity returning to its original interior dimension after the width of the disk becomes less than the originial diameter at the location. In a preferred embodiment the top and bottom portions are identical.
