CD Material for Cycles [Blender 2.93] - 1.0

A while ago I had to make a commission and I managed to make this material with Blender, which turned out better than I expected - and since I got a few questions about how I did it I thought I'd share the .blend files with everyone.

The project is probably a bit messy because I am not an expert and I'm still learning, and if you have any feedback/suggestion I would love to hear it!
Check this artwork page on my ArtStation to get some details about the project and how it works. Let me know if you have any doubts or questions.
