Hi. This question will be a little different and I am not sure if it is in the right area. I bought some used cds on ebay thinking they were original. I now think they are copies. Two of the cds have TDK Certified Plus on them. Would the maker of the original cds use these cds or are they only the kind you would burn on your home computer? I just want to be able to prove if these are originals or copies.
Thanks for your help.
