This is a hard learnt lesson which I am passing on - no doubt someone will refer me to a previous thread on the same topic which I failed to heed - so please learn from my experience.
In August 2001 I completed a major scan of my portfolio material and saved the unadjusted files on CDs. These CDs were then individually placed in paper "slip-sleeves" supplied by a reputable manufacturer - TDK. Since then the CDs have been stored in a cool, dry place and were I assumed, a reliable archive of my material. WRONG. All the Cds are now unreadable. Examination shows there has been an interaction between the sleeve and the surface of the CD which now looks as if its has a bad attack of moire pattern! Furthermore I have found similiar "staining" on CDs stored as recently as Aug 2002 Clearly the only way to store CDs are in a jewel case where no contact is made between the surface of the CD and any possible contaminents in paper sleeves etc. Obviously there are other factors which could affect the CD - humidity at time of creation etc - but it is clear that with so much at stake over long term storage one should reduce all possible risks. I have failed to do so and paid the price - so do not use slip sleeves for CD storage.
