A reminder that CD-ROMs are pressed from glass masters, not burned like CD-Rs. I wonder if anyone has tried something like this with burned discs, though.
Yes, my point, if the answer is that there is no way this works without every disc being different.
It was not possible to manufacture at the time at scale.
The multisession standard actually afforded the possibility of CD-PROM; a hybrid disc with a pressed read-only session followed by a writable section. It was only used for Kodak Picture CD (not the same as Photo CD) to hold software in the pressed session. It also apparently standardized a magneto-optical hybrid that never made it to market.
