AFAIK only (some) CD-Rs had a gold reflective layer, factory-pressed CDs use aluminum - so no gold, no silver. It's a bit strange that they started the whole project apparently without having a clue whether it would have actual practical value ("We used gold CDs, and we want to explore silver-based CDs, which I believe are more common.").
- awiesenhofer 4y agoThere are lots and lots of gold CDs out there. Sony, Verbatim, Kodak, etc all sold these "premium"/"gold"/"archival grade" versions. Even if its not billions like with aluminium, its definitly millions and a vast ressource to recycle. Sounds like a lot of practical value to me.
