Well, hearing an error on an audio CD might be difficult.

If cost is no object, you could have the data pressed to a mastered
CD, as opposed to burning a CD-R at home. The "real" aluminum

than the aluminum foil version. Are there any CD mastering plants
that give you an option of true gold foil, to avoid oxidation?
