Dear Colleagues,

I have posted several items in the past in regard to the horror stories
of the actual or anticipated problems with the longevity LE of CD's but
the article available at which states:
"The Dutch PC-Active magazine has done an extensive CD-R quality test.
For the test the magazine has taken a look at the readability of discs,
thirty different CD-R brands, that were recorded twenty months ago. The
results were quite shocking as a lot of the discs simply couldn't be
read anymore." sends a shiver up my spine. The article is also
documented in greater detail in the November 2003 edition of APC
"Australian Personal Computer" on page 18. There is even more bad news
[if that is possible]"Recordable DVD's are even more susceptible to

For those who speak Dutch or have a good translator, the Dutch PC-Active
site for the original article is

The statement by RAND researcher, Jeff Rothenberg in Scientific American
some years back, "to say that digital information lasts forever-or five
years, whichever comes first" appears to be a truism if this Dutch
research proves to be accurate.

Maybe the transfer of digital data to 16 or 35mm microfilm is the only
long term viable answer to store our archival data requirements as the
Microfilm and other Preservation Professionals keep telling us!

Yours Sincerely, Laurie Varendorff
