If you want CDs to be uncopiable, the next best thing for you may be to make them unreadable except to you and a few of your friends. If its not going to be a music CD, you can try just encryptign the contents (Good ole PGP should do the trick.) This way only you and the people you give the key to will be able to see the data on the CD.

(Create a seperate key for the CDs, otherwise people would be able to decrypt ANY of your files, not just the CD Contents.)
