Some copy protection systems, like the PlayStation, rely on the physical location of the tracks to encode extra data, extracted via monitoring analog servo corrections. A full optical disk archive format would have to consider mapping at least some of that data.

Stuff like Wii/GameCube yes rely on a laser-cut BCA (readable barcode) and laser-created marks that cause errors in the bitstream. Actually encoding physical copy protection schemes in an archival format is extremely difficult.
Some protections rely on the physical angular position of sectors in the single track bitstream. A format encoding that would have to encode the raw EFM bits *and* a detailed timing code encoding the exact coordinates of the data on disc.

Thankfully we don't *actually* need that level of duplication for accurate emulation.
Thanks. Twitter will use this to make your timeline better. UndoUndo

Afaik these systems can all be handled pretty simply and just amounts to storing some metadata to reconstruct answers to challenge/response protocol similarly to how you can rebuild the physical bitstream from decoded data on the fly instead of storing the expanded bitstream form
