As long as people have floppies and CDs and DVDs they need something to access them. Combining DVDs, CDs and floppies, I have well over 3000, and I know people whose libraries are measured with 5 digits.

I gave up on floppy/CD/DVD RW as long term offline storage when I discovered "bit rot". I had around 600 CDs (several years ago) of data stored (personal videos, photos, music, multimedia etc) all burnt to CD and/or DVD. It was all "stored properly" out of the sun, in individual jewelbox cases etc. None of it survived more than about 5 years. Most was unreadable within 3 years of the burn date. A couple are still valid after 10 or 11 years though... the rare few.

The choice of CD/DVD plays a role. For example: http://www.kmgdigitalinc.com/premium/gold-preservation-system I have not used these. But they have been around a while. -- Yours sincerely, Roger Oberholtzer Ramböll RST / Systems Office: Int +46 10-615 60 20 Mobile: Int +46 70-815 1696 roger.oberholtzer@ramboll.se ________________________________________ Ramböll Sverige AB Krukmakargatan 21 P.O.
