What would cause the space to suddely shrink like that? When the disks are this size, basically all they could do is alter the wavelength of light the laser and disk uses. Infrared is CD, anything shifted further down would either make it less than CD capacity or just plain not work. DVDs use red light, anything shifted higher would allow for higher capacity (for example, blue ray) or just not work. Any encription scheme wouldn't do a thing. They could have a standard TOC that says the disk has this much data and doesn't even map out all the actual data, but that's been done before and it can be overcome.
So, any exclusive format they use, I really can't see how it would reduce the capacity.

"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
