The above values, calculated according to accelerated aging tests (in advertisements), have nothing to do with reality.
We've tried to gather a bit of information from users in Afterdawn.com.
Many CDRs seems to die after about 3 years, regardless of the brand or dye. However, it is very difficult to find dead Tayo Yuden. Only one unconfirmed report so far.
But I've found something interesting in my CDRs. The 25 dead CDRs (21+5) I've got are all silver, and my 4 Gold CDRs from the same time are still in perfect state.
All dead CDRs have no visible scratch nor fingerprint and were all playable after being burned.
Experiences, anyone ?
