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.

Here are a couple of articles.  It was a wide spread practice in the late 1980's & 1990's.  Many believed in it and many didn't.

They are not "damaged" in any way.  They should still play fine.
"the colors on the CDs you acquired are actually reversed and that will unfortunately hurt the sound of all of the CDs, rather than improve the sound."
IMHO, it doesn’t matter one way or the other, but it certainly won’t "hurt" the sound.

Many actually started using black or purple to color CDs with, instead of green.
