Last week I finally got rid of a lot of my old CDR/CDRWs. You know the CD recordables en rewritables. According to my memory the life-expectancy of data on this type of media would only be like 5 to 10 years. Boy what was I wrong :)
Some of my media dated back till 1997. This was both CDR and CDRW and they were all still readable. I think I had more then 100 CDs which I copied and with only 1 I had some troubles reading the data from it.
The nice thing is that some of them were real cheap at the time of purchase while others were quite expensive. But in the end I did not notice any difference.
This link reports a recorded lifespan of 50 to 200 years for that type of media.
