     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved compact audio 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 compact audio disc storage apparatus 10 of the instant invention essentially comprises a plurality of tray members that are arranged for stacking in a vertical nested relationship, as illustrated in FIG. 4 for example. Each tray member includes a floor plate 11, with a spaced right and left side wall 12 and 13 respectively that are arranged parallel relative to one another and orthogonally mounted to the floor plate 11. A first rear wall 14 is spaced from and parallel a second rear wall 19, wherein the second rear wall 19 is orthogonally mounted between rear terminal ends of the side walls. A storage cavity 15 is defined between the first rear wall 14 and interior surfaces of the side walls, as illustrated. An entrance opening 16 permits access of various audio discs into the tray structure, as exemplified by audio disc 27 (FIG. 4) that is positioned adjacent and in contiguous communication with a plate member 18 of a plunger drive 17. The plunger mechanism 17a is positioned within a housing between the first rear wall 14 and the second rear wall 19. To each side of the plunger mechanism 17a is a respective right and left cavity 20 and 21 mounting a respective right and left mounting flange 25 and 26 that is received within respective flange recesses 25a and 26a through a floor plate of an overlying tray. The right and left walls each include a top respective right and left top surface, with each right and left top surface mounting a plurality of projections defined by right and left projections 22 and 23. The projections 22 and 23 are received within respective side wall projection receiving cavities 24 positioned through lower surfaces of the side walls. These projections permit proper registration of the trays and alignment of the trays when in a stacked relationship, as illustrated in FIG. 4. 
     In use, a compact disc 27 is positioned within the storage cavity 15 against a plate member 18. To remove the disc member, particularly when the trays are in a stacked relationship, an individual merely manually depresses the tray against the associated plate member 18, wherein the plunger drive 17 projects the disc from interiorly of the cavity 15. 
     FIGS. 5-9 illustrate a modified apparatus utilizing modified trays 10a, and includes a support base 28, as illustrated in FIG. 5. The support base 28 includes a base top floor 29 spaced above and parallel a base lower floor 35 defining an enclosed cavity therebetween (see FIG. 6). A base right side wall is spaced from and parallel a base left side wall, with the base rear wall 34 defining a receiving pocket for the modified tray members 10a, as illustrated in FIG. 7. The base top floor includes respective right and left base projections 32 and 33 respectively to be received within the respective side wall projection receiving cavities 24, in a manner as discussed above. The enclosed cavity 36 includes a battery 37 and an illumination bulb 38 operative through a switch 43 to effect selective illumination of the illumination bulb 38. A right and left fiber optic cable 39 and 40 respectively is directed through the cavity 36 and is positioned through the top floor 29 adjacent an intersection of the rear wall 34 and each respective right and left side wall 30 and 31. These right and left fiber optic cables 39 and 40 are to aligned with respective right and left fiber optic cable segments 41 and 42 respectively that project through each of the right and left side walls 12 and 13 of a modified tray member 10a. The predetermined width defined between exterior surfaces of the right and left side walls 12 and 13 are substantially equal to a predetermined further width defined between interior surfaces of the right and left base side walls 30 and 31 to align the right and left fiber optic cables 39 and 40 with respective right and left fiber optic cable segments 41 and 42 of each modified tray 10a. In this manner, when the trays are properly aligned in a manner as illustrated in FIG. 7, the fiber optic cable segments 41 and 42 are in linear alignment to permit light to be visible through an upper terminal end of an uppermost tray member 10a to provide visual indication of proper alignment and registration of each of the trays relative to one another. In this manner, utilization of the structure is not undertaken until such proper alignment is checked to ensure safe storage when there is compact audio discs 27 to be contained within the apparatus. 
     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 relationship 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.
