Does anyone know about putting marker on CDs?


I have been given a large number of CDs to sell. Many of them appear to have black marker around the edges. One has green marker in the center. Does anyone know if this would have been done on purpose as some kind of enhancement perhaps? I am wondering if this is a known practice or if I should consider all of these CDs as damaged.

You can remove Permanent marker by applying Dry Erase marker on the top and wiping it off.
You could contact RTI and see if their machines could remove the ink.
I bought their Pro model to remove scratches and polish my aging discs.
