You can ask Sony and see how that worked out for them.

A) melt it down (breaking it might not be enough)
B) encase it in that stuff that the military uses to protect
classified circuits
C) lock it down through some mechanism that you *really* trust
(taking into accounts that guards might be corrupted, or that
tactical nuclear warheads might be used to blast through whatever
physical barriers one might erect.)
D) don't write any information on it to start with
E) There is no (E).
Pretty much everything else can be copied, including:
- any encryption scheme (you wanted to protect the *CD* from being
copied, not the -information- on the CD)
- any scheme involving writing in non-standard formats
- any scheme involving deliberate disc errors or writing
with custom spacing or custom pit sizes (all can be duplicated)
- any Digital Rights Management scheme, including Sony's
(doesn't prevent the CD from being copied -- at *most* prevents
the information on the copied CD from being useful.)

You cannot. Why do you want to?
(Of course you can go the Sony route and put a virus onto the CD. Not that
it works, but think of the great publicity you will get.)

Break it in the middle.
