Re:Re:Re:WHAT TYPE OF CD SHOULD I STORE DIGITAL PICTURES TO?

Like magnetic media, the material used to store the data on CDs deteriorates over time. In the case of CD-Rs, it's generally decades.

However, CD-RW uses thinner layers, that can be burned away, one at a time (that's why they're ReWritable).
This makes the disk less stable. The material deteriorates in months.
