What is discoloration that follows the grain of a CD?

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.

This thing?

Assuming it is then the disk itself can no longer be salvaged. The only thing to do in this case is to rip the data from it and hope that it still "rips fine" as you have luckily found for your disks. I had one album that had tiny holes and could no longer be read.
