One thing i learned recently about optical disks disturbed me. I had
always taken the most care to protect the data side of the disk. I
found out that the most fragile side is actually the one with the
label. It's the one closest to the actual media. A scratch there--one
which might not even glitch a reader if it were on the other side--can
expose the metallic layer to corrosion.

Yeah, and a piece of sticky tape may pull it off entirely on CD-R/RWs!
