     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved disc storage apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the disc storage apparatus 10 of the instant invention essentially comprises a support housing 11 having a support housing floor 12, including a housing first side wall 13 spaced from and parallel a housing second side wall 14 that are spaced apart a predetermined spacing. The housing includes a semi-cylindrical upper rear wall 21 defining a semi-cylindrical cavity 15 therewithin accessed into the housing through a cavity entrance 16. The cavity entrance 16 is defined between parallel and coextensive first and second side wall vertical forward edges 17 and 18. A cylindrical support drum 23 is rotatably mounted between side walls, with the support drum having first and second end walls 24 and 26, with the support drum axial bore 25 orthogonally oriented relative to the end walls and coaxially directed through the drum. A concentric array of end wall mounting bores 27 are directed into each end wall concentrically about the axial bore. First and second side wall bores 19 and 20 directed through the respective first and second side walls adjacent the first and second forward edges 17 and 18 have the bores coaxially aligned to receive respective first and second axles 28 and 29 through the respective first and second bores 19 and 20. The first and second axles 28 and 29 include respective first and second axle handles 30 and 31 that are mounted fixedly thereto. The axles are rotatably mounted through the first and second bores while fixedly mounted within the axial bore 25 of the drum 23 to permit selective rotation of the drum by rotation of either the first and second handle 30 and 31. 
     The mounting bores 27 of each end wall are provided to have a mounting bore 27 of the first end wall coaxial with a mounting bore of the second end wall 26 to receive a disc holder 32 thereon. The disc holder 32 is illustrated for purposes of detail, but it is understood that each coaxially aligned pair of the plurality of aligned pairs of mounting bores 27 of each respective end wall are arranged to secure a plurality of such holders 32 in a circular array about the drum 23. 
     The disc holder 32 is formed with a support plate 33 having respective first and second mounting rods 34 and 35 positioned therebelow in a coaxially aligned relationship relative to one another and parallel relative to a lower edge of the plate 33. First and second side walls 36 and 37 orthogonally mounted relative to the support plate 33 are substantially coextensive therewith, with the lower edge of the support plate having respective first and second spring fingers 38 and 39 in biased abutment with the support plate between the side walls to secure a disc (not shown) secured between the spring fingers and the support plate. The spring fingers, as illustrated, are normally biased in engagement with the support plate to permit ease of mounting and dismounting of a disc thereon. 
     The cover hood 40 of the invention includes hood first and second side walls 41 and 42 spaced apart the predetermined spacing in a parallel coextensive relationship having a hood semi-cylindrical rear wall 43 defining a hood cavity to receive the drum therein when the cover hood is directed into engagement with the first and second vertical edges 17 and 18. The cover hood includes a first and second spring plate 46 and 47 arranged in parallel relationship below the respective first and second side walls, with the first and second spring plates biased in a parallel relationship having respective first and second plate rods 48 and 49 that are coaxially aligned relative to one another and orthogonally and fixedly mounted to the respective first and second spring plates 46 and 47. Accordingly, the first and second plate rods 48 and 49 are mounted to respective first and second cover mounting bores 44 and 45 of the support housing 11 below and forwardly of the first and second vertical edges 17 and 18. In this manner, pivotment of the cover hood forwardly maintains the cover hood in engagement with the support housing 11 due to the biased relationship of the spring plates 46 and 47. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
