I was throwing away yet another one of my kids DVDs today (scratched beyone hope) when I had the inspiration for an invention. Scratch-proof method of storing and playing DVDs and CDs. The idea would be quite simple to execute - simply emulate the old floppy disks from our old PCs. You know - a hard outer case with a sleeve that opens inside the player, and then closes when you remove the disk. I figure an entrepreneurial person could invent an outer shell that DVDs and CDs could be placed in. Then all that needs doing is to create the player that could accept the shell and play the disk within like a floppy does. Seems simple enough - why do you suppose it hasn't yet been done?
