Another longevity issue with CD/DVD media is mold and bacteria. Apparently in humid climates anywhere, there are molds and bacteria that will eat the data layer. Sometimes within weeks. Cool & dry is best for storage. Don't know about the glue eating the data layer. I thought labels and adhesives just took off the reflective layer causing a loss of readability. Data is still there if you can replace the reflective coating... Sanford's Sharpie brand of markers are OK for writing on the media.
