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.

RFID type circuit. Would need to calculate the antennas length to find the operation frequency. The barbell shaped thing at the top is just a bridge, the thing on the right is the circuit.
