What is the current wisdom on long term (10y, eg 50 or 100y) storage of
music (pictures etc too) as CD's or DVD's go?
eg which brands, which technologies (CD or DVD, gold plated etc)?

TIA

My current practice is to buy known-good (i.e. not re-branded
counterfeits) brands like Taiyo-Yuden and re-copy them every
3-5 years. I have no faith in the long-term "projected lifetimes"
claimed by manufacturers.

Gold plated might have some long-term value, but I'm not willing
to do the "experiment" on MY live data.

Mitsui's offshoots (MAM-A and MAM-E) claim the longest lifespan (200
years) but their discs also have comparitively high initial error rates.
Whether you accept their claims depends on how much you trust accelerated
ageing tests. I've seen independent accelerated ageing tests that appear
to support Mitsui's claims but these tests may not catch all the
mechanisms that occur during ageing.

I have a few 10 year old T-Y discs that still show low error rates but
they don't come out as well in these ageing tests at around 80 years
predicted lifespan.
