The awful truth about CDs, do they have the same shelve life as LP's ?

The answer is properly not. Recent studies have shown that the chemicals used in their manufacture of CDs have reduced their life expectancy to ten years, not all but many, as per Paul Mcgowans email. The suggestion was given that if you have suspect CD's they should be re-copied. But my question is how do you identify these? I can tell you that I have a great deal of LPs and I can play anyone of these with great success and some are 40 years old. This no doubt would give some audiophiles another good reason to hold onto their belief that LPs are the way to go.

Hi,

My 2 cents. I have a few commercial CD's from 1985 that developed spots/deterioration in their inner layer(s). I cannot feel then on the outside layer.

The were manufactured in USA by WEA Manufacturing Inc. record label is Elektra/Asylum. 

I keep all my CD's in binders. So far it is a real minority that are damaged like this. My opinion is that it all depends in the quality of the manufacturing.

With CD-R's (mixes), I have several that have gone really bad with time; to the point that I have to throw them away. It probably was the qualityof the CD-R materials back then.
