    Music CDs or data? Music CDs have built-in error correction, data CDs don’t. You can certainly extend the lifetime if they’re stored in the dark in a cool, dry place (UV light, heat, and humidity all damage the dye that gets burned to encode them) but they’re not reliable archival storage without error correction.

      Data CDs actually use even more robust error correction since they use interleaving in addition to FEC since they don’t need to scan in “real time”
