  Gold doesn't oxydize. AFAIK that is a problem that sometimes affects aluminium based discs, when the polycarbonate seal is defective. If you want to be really sure of maximal shelf life, you'd use glass instead of polycarbonate as well - the manufacturing technology exists: https://www.theabsolutesound.com/articles/the-2000-cd-made-from-glass-1/ https://www.theabsolutesound.com/articles/the-2000-cd-made-f... But all of that is really not relevant at all for backups because the CD-R dyes will degrade long before the reflective layer. The shelf life of the reflective layer is an issue when talking about pressed discs.

    Fascinating article that, it borders on the HiFi madness but does so in a way that it leaves some wiggle room for an actual effect. Pity he didn't take the time to do a 'diff' between two signals on a sampling memory scope. If there was a difference in the output that's where it would show up the clearest.

      Yeah, the audiophile angle is... Strange. But my point was really that glass would last much longer than polycarbonate.

  Because gold is incredibly non-reactive?
