A package comprising a case which comprises a bottom member and a cover member, and a plurality of disk-form magnetic recording mediums, each having a central hole, which are contained in the case in a stacked state one on another while an upright pillar standing on the center of the bottom member is relatively inserted into the central holes of the disk-form magnetic recording mediums. The package may be tied from the outside by binding means or may be wrapped by a plastic film by means of a vacuum packing. The disk-form magnetic recording mediums packed in the case are protected from the dust and the moisture perfectly, and the damage of the recording mediums caused by the rubbing therebetween by vibrations or the like during the transit can be prevented by the upright pillar inserted into the holes of the recording mediums.

An improved package for holding and storing a plurality of disk-form recording mediums, each having a recording area that can be stacked atop one another without spacers therebetween, comprising: a bottom member having a flat, circular surface which has an outside diameter greater than the outside diameters of the recording mediums to permit such flat surface to contact the entire recording area of a recording medium, the bottom member further having only one projection ring extending generally perpendicular from the flat surface of the bottom member, the projection ring having an exterior surface of a single, uniform configuration, the inside diameter of the projection ring being greater than the outside diameters of the recording mediums and less than the outside diameter of the bottom member; a plurality of spaced apart legs fixed to the bottom member along its peripheral edge, each leg having an angulated side configuration; a pillar fixed to the bottom member at its point of center and extending perpendicularly therefrom to a height that is at least equal to the height defined by the recording mediums when stacked; a ceiling member having a flat, circular surface that is parallel to the flat surface of the bottom member the flat surface of the ceiling member having an outside diameter that is approximately equal to the outside diameters of the recording mediums and disposed around an interiorly concave portion of the ceiling member which extends about the flat surface of the ceiling member, the interiorly concave portion being configured and dimensioned to receive the pillar; a cover member having a surface configured in a truncated cone form, the truncated portion of which is fixed about the ceiling member and includes a plurality of spaced apart cut-off portions, each cut-off portion having an angulated side configuration, the distal portion of the cover member opposite the truncated portion having only a single, uniform interior surface configuration, the interior surface capable of frictionally engaging the exterior surface of the projection ring; a plurality of spacers, one of which can interface the flat surface of the bottom member and one recording medium and another of which can interface the flat surface of the ceiling member and one recording medium, each spacer being configured and dimensioned to transmit compression forces from the flat surfaces and equally across to the entire recording areas on the recording mediums; binding means for binding the cover member to the bottom member; and wrapping means for wrapping the ceiling member, cover member, bottom member, legs, and binding means all within a vacuum sealed environment.
