I've seen patterns on CD's that I have burned lately too. For me the  
pattern is rings that are about 1/2 inch in diameter and they  
alternate in shade. Kind of like how you see grass cut on a baseball  
field. Everything verified fine.

My disks are old also, but probably not much more than a year.
