Brace yourself: the shelf life of a burned CD-R or CD-RW is likewise uncertain...

Oh yes, and I meant to add: and then there's the question of whether you will still have a *reader* for those media ten or twenty years from now. Eleven years ago, I had to make a point of specifying that my 3.5in floppy should be drive A on my new machine. Now, good luck trying to find a 5.25in floppy drive at all. And the days of 3.5in floppies are (finally) numbered, with USB flash drives likely to kill them soon. Another reason to regularly recopy something you want to save permanently is simply to get it onto modern media.
