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.
Music. I have some data CDs I burned in the mid 2000s, that I booted up a few years ago (Linux live CDs). I don’t have any data CDs from the 90s though. IIRC, ISO 9660 does have error correction.
Edit: I just looked it up. ISO 9660 doesn’t have error correction, but the underlying system, CD-ROM Mode 1, does have error correction.
