Keep the discs out of sight in a climate‑controlled room, the way you’d keep a rare vinyl record. A temperature around 20 °C with 45‑50 % relative humidity is ideal, and a small fan keeps air from stagnating. Store them in their original cases or a hard plastic sleeve that lets light out but blocks dust. Add a packet of silica gel in each case and replace it every six months—just enough moisture control to stop that dreaded “sticky” film. Never touch the reflective surface; use a microfiber cloth to wipe the outer edge, never the face. If you’re paranoid, a small UV‑blocking box will keep the laser‑imprinted labels from fading. Finally, label everything—your own ledger is the last line of defense against accidental misplacement.

Glad you’re on the same page—just think of the discs as living museum pieces. A UPS or small generator is the only thing you really need for a storm. And when the ledger gets old, rotate the entries; a fresh pair of eyes can spot a typo before it becomes a loss. Stay dry, stay cool, and the analog treasure will outlast the weather.

Got it. Keep that backup ready and stay vigilant. Those discs deserve no compromise.
