I searched their site but couldn't find one picture or reference to a CD from 1705 AD. Can they be sure they last 300 years?
Seems like a good idea for long term storage.

Seeing as I have anything from 1 week to forty years left I really don’t give a toss about a CD that will last 300 years

We'll be lucky to have anything that'll read CD's in 25 years.

Just before I left for HK, I was doing a more thorough than usual data backup, and discovered an early batch of TDK CD-Rs unreadable (dating back to at least 8 years). They were green reflective (which translates into ??? as recording layer); while an older batch of Mitsui Gold's (gold reflective layer) had remained fine. So IMO it's not all about marketting gimmicks and bogus claims - if those bogus claims have a shred of validity I'd certainly be interested in longer archival life from optical media.

Nothing in this world about the media of DVD or CD can be guaranteed last for such 300 years, it's just a marketting gimmicks.

Mostly early CDs were not good... from what I remember, the bright green and blue azos were the worst to deal with.
With Kodak's experimentation into gold, silver, and then gold & silver azos, they found a winner, and most azos started to become a variant of green but with either silver or gold or both combined in the process... I think that's what the Verbatims are, anyway.
From what I recall, the azo that the recorder writes on for the CD / DVD is organic, or rather has some organic components in it, so things like DVD rot or CDs dying if not kept well is always a possibility no matter what the brand or CD type.
