In truth, finalizing has nothing to do with DRM, just with the
structure of the CD and DVD file systems. Basically, they don't really
have a directory until they are finalized. However, the originating
recorder knows its own particular way that it encodes discs, so it
*can* read them.
That's why the recorder can add more data to the disc until it's
finalized, and why other players can't read them.
If someone had spec'd a sort of preliminary directory and required all
CDs and DVDs to use it and all players to understand it, then all
players could read unfinalized discs. But I guess writable discs came
along after the original read-only discs were spec'd, and it was too
late. I am speculating on this part.
