Prof Dave,
 Slashdot has a thread on this topic:
http://slashdot.org/articles/03/08/24/1253248.shtml?tid=126&tid=137&tid=198

Actual news is reported in the following link
http://www.cdfreaks.com/news/7751

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:

Roughly translated from Dutch:

The tests showed that a number of CD-Rs had become completely unreadable
while others could only be read back partially. Data that was recorded 20
months ago had become unreadable. These included discs of well known and
lesser known manufacturers.

It is presumed that CD-Rs are good for at least 10 years. Some
manufacturers even claim that their CD-Rs will last up to a century. From
our tests it's concluded however that there is a lot of junk on the
market. We came across CD-Rs that should never have been released to the
market. It's completely unacceptable that CD-Rs become unusable in less
than two years. .....
