OT but possibly important: shelf life of CD's

Kurt Gerecke, a storage expert at IBM Deutschland Gmbh, is quoted in the
January 20 issue of Computerworld Canada as stating that burned CD's,
unlike pressed original CD's, have a shelf life of 2-3 years, and
recommending that for long-term storage magnetic tape should be used.
He would seem to be a plausible source! Is there anything else current
in the news about this? (I don't get many of the trade mags). If it's
true - what are the implications for cold storage? Or are CD's not used
all that much? (I'm asking because it's something I've never had to
worry about. I have 30-year-old 800bpi tapes that are still readable!)
