I've had about 200 CDs from the 80s corrode, some very seriously. They were all pressed by PDO (Philips Dupont Optical) in Blackburn, Lancashire UK. ALL were classical titles and most, fortunately were replaced free of charge by PDO. The major labels with the problem were Hyperion, ASV, Unicorn and DG Archiv. A corrosive chemical was introduced into the manufacturing process that attacked the aluminum layer in the CDs.
More reports-How many corrupted CD-R's with time?
Answered another post where member reported that some of his CD-R's srated to go bad after just 3 to 4 years and thought I could get some more feedback posts.Imagine that favorite LP or tape collection that you expected to get 20 years or more out of start to go bad.Some of the Cd's I bought in 1983 still play though articles said doom and gloom ahead do to oxidation etc.But Red Book CD's use a thin plastic wafer punched with it's pits and a sprayed aluminum that has help up pretty well.But their is obvious difference where with recorded CD's you are essentialy melting a chrystaline metal (re-recordables overwrite simply increase laser temperature to erase previous data).Want to know if has happened with others.Some have said it is dependent on the brand of CD-R's used,the type of dye etc but I am not so sure.The RIAA will juimp with glee if CVD-R's carp out while I and others will weep.Until corprate data needed to stay intact will I think the problem (if it exists extensively) will change things and I am not sure Blue Ray or HD CDR's will address the problem because not enough time has elaspsed before they lose those files.Reports?Thoughts?
