Many, many threads on this subject, & why Not to use sticky labels. I gave up on them long ago for various reasons, & now I either use a cd/dvd marker, or if I want to make fancy discs, I will use my epson r220 printer, which prints directly onto the disc.
You would need to use special printable media, but it is not really all that much more in cost, esp. when you figure you would be buying labels anyway.
There are small labels that affix to the center "clear" part of the hub, but unless you can read tiny, tiny print, I don't feel they are very useful.
