In advance I apologize for my lack of correct terminology. I noticed on some of the albums I own, both new and well used various spots of discoloration appear on the information side of the disc. It is incredibly subtle and seems to follow along the CD's grain or rings sometimes veering off slightly to make a larger splotch.
Despite this odd aesthetic appearance the albums play and rip fine. I'm curious if the discoloration is a result of the method used to press the CD or perhaps some sort of warping developed over time. Thanks. |

Just for fun and a bit OT try scanning a variety of CDs.
