    Put it in a case like an old floppy disc.

      What of you put it on an enclosure that has the disk(potentially even more stacked on top of each other) plus all the hardware needed to read the disk. Then all you would need is to provide power and plug in a data cable.

        Or like a UMD or mini disc? Still have to insert it into something to read and write, but the discs themselves are enclosed and protected unlike CDs and DVDs and Blu-ray. Basically they’re floppy disks, but instead of magnetic tape inside the shell, it’s an optical disc.

          I like this and for what it will likely cost I’d hope would have it. Other than scratches, dust, oils from touching, light and other contaminates are the biggest threat to longevity.

      Believe it or not, first gen DVD-RAM came exactly like this. But manufacturers cheaped out / wanted the drives to be more easily compatible with CDs. So the caddys were scrapped.

          There is one on the Wikipedia page.

          https://en.wikipedia.org/wiki/DVD-RAM

          Due to the caddy nature I believe there were plans or limited availability of double-sided disks. That would have made it so much more appealing I think.
