The present invention is a disc media storage and retrieval system for safely and efficiently storing and conveniently retrieving specific disc media from a plurality of disc media stacked on a central column or spindle. Modified disc media are rotationally aligned on the spindle using corresponding alignment protrusion(s) formed on the spindle and notch(es) on the inner chuck hole of the disc. Accordingly, disc media is further modified with the addition of indexing notches on the outer circumference of the disk, such that each disc within the system is provided a unique notched-index. The aligned stack is protected by a cover member that forms a disc lifting device. A disc of interest is indexed and retrieved from the stack by rotating the cover member relative to the disc stack thereby aligning the disc notch-index with the lifting device. When the cover member is raised, the lifting device separates the stack at the disc of interest. These innovations and modifications to the disc media provide improvements in disc storage and retrieval over existing spindle-type disc media storage systems.
