The disc is otherwise printed like a “normal” Bluray, but there is this metallic quadruple ring on top. The image is from the “proof” of a scene release, so it might have something to do with being an early release.

Some kind of anti-removal or tracking measure, except applied directly to the disc instead of the sleeve or case?
It’s an anti-theft device. All the DVDs and games I get from the library have them.
This is correct. All DVDs I borrow from our local library have these.
It looks like an NFC antenna. But I can’t explain why would one be on a disc.
Does it provide some additional data to a player? Or helps the publisher track it somehow?My library does this for checkouts, and to make sure you arnt taking an un-checked out movie
