Why are there Circles on Blu-ray Discs?!

The good news is that this residue will come off with a simple cleaning, but it may also return if you continue to use the original case. If the residue returns, or if you just don't want to potentially deal with this issue again, you can buy high quality replacement cases such as those made by Viva Elite. You can buy them at multiple online sites, including ebay.

Ah ok this comment alongside the top image is starting to add up now. So basically the circles are from the manufactureing process, it’s just so odd that when I buy them new there aren’t any but months/years later they are present on the back of the disc. I guess that’s what’s throwing me off. But yeah they clean off and don’t seem to affect the disc in any way. At first I though disc rot and got all freaked out. Lol I have crds from the late 90s early 2000s that still look and work flawlessly. I may have a few GameCube games with disc rot due to the person I bought them from not taking care of them and probably leaving them in extreme weather (ugh some people). Also always though disc rot could transfer to other discs....god I hope that’s not a thing lol
