I think we'll be in as good or better shape playing back CDs in 50 years as we will be playing back reel tapes in 35-40 years which is approx the 50-year time frame that LoC was still advocating transfers to 2-track tapes. There are just too many, and they're not going to all break. As with any media, as the supply of machines dries up it's the archive's responsibility to migrate/reformat before they cannot. I think we've had this discussion before <smile>. Cheers, Richard Richard L.
