For the first time I recently learned that most write-able CDs and DVDs have a limited life of 8 years or so. Apparently the metal in them corrodes in time. But, it is said, better ones are available. I tried the Internet, but apparently am not using the correct description to find an answer. Where can if find the longer life ones?

Search for Archival DVD Media. Here's one company called Delkin that make them, and here's Verbatim Ultralife, another option. The most popular seem to be Taiyo Yuden/JVC Brand discs.
I remember about some company creating writable media made out of stone, or something to that effect. It was supposedly the most reliable and resilient storage medium and was predicted to last for decades.
Anyway, archival media - it almost sounds like a gimmick, but I'm sure there are companies that create writable media of a higher quality that maintain their readability for longer. I know Blu-ray discs were engineered to be more scratch-resistant - something called hard coating. Some Verbatim-brand media DVDs (not Blu-rays specifically) have this hard coating, too, so you may want to took into that.
Otherwise, there are much more reliable and versatile storage media in the form of hard disk drives and solid state drives, though they can run on the expensive side. I recommend a mix of HDD/SSD and CDs/DVDs/Blu-ray discs for data archives. Of course, taking utmost care of your backup media will lead to a much longer life.

I think I started using CD-Rs when I first got my new computer in 2001, the drives on my Mac read the old old CD-R but my PC has issues sometimes continually trying to read it. Same goes for DVDs apparently and they hardly have a scratch on them.
its not the scratches that erases the data (it does if you are not careful with them) . its the sunlight . keep them out of the sun / in the dark . I have had a few copied cd's erased by the sun.

I didn't know about this. Interesting!
Most of the cd's I have are about 8 years old, I've been backing them up on a hard drive and DVD discs. They have held up well, just a few minor problems with a couple not being read by my drive but an old drive read them fine.
