how do i make a cd's so they can not be copied?

I know that a lot of CD burners can't make a disc with subcodes like are used in CD+G karaoke discs, but they can read them. If you could come up with some scheme that used these subcodes as an integral part of using the CD, you could eliminate copying on most, but not all CD burners

you can burn it, then scratch the crap out of the bottom so it can't be read or copied. now that is some piracy protection.
