Norm notes a very cute attempt to rip vinyl records via a scanner (from /.)

There are several reasons why this guy's attempt has problems, but the idea is very cute.
This prompted a discussion about storage life as a function of media (vinyl is probably better than early CDs). Compiling a list is great sport, although it is difficult to come by hard data. Good low acid paper will easily go a millennium given good storage conditions, but magnetic tape can have serious problems in as little as a decade or two. Compact discs are better than those that were made in the 80s, but squeezing 100 years out of them may be difficult. CD-Rs and CD-RW seem to be much worse. There is some evidence that ten years may see serious corruption.
When people are interviewed after disasters they usually mention their relief to save three things - family, pets and photos. Photos can certainly last on the order of a few hundred years given good conditions (and the right choice of film), but some of the paper/ink combination used in inkjet printers are awful after a couple of years (I speak from experience).
How should one store documents and photos for a few generations? How about ten or twenty generations? If the documents are digital files, how should they be moved, backed up and converted? These are very interesting and non-trivial problems.
