I'm afraid it's not. I've googled around but didn't manage to find such a document. Only opinions (both in favor of tapes and DVDs), but nothing proven. > Ask a DVD manufacturer how long he will guarantee the data on a > DVD. I suspect that there is *no* guarantee. Just an example: http://www.verbatim.com.sg/technotes/DVD-RW_Lifetime.pdf > If you ask a good tape > manufacturer (HP), they will tell you 30 years. However I think that neither guarantee is a real guarantee, but their are just marketing strategies. When we'll be in 2035 I'll try to go to HP with a failed tape I've bought last year and see if they will refund me. :) I'd like to try the same in 2056 with Verbatim. :) After having read various opinions it seems that the longest lifetime of DVDs comes with Taiyo Yuden DVD+R and good storage practices (no sunlight, DVDs kept in vertical position, little umidity, no more than 20 celsius degrees).
