is there a tool or program that is able to authenticate if discs are genuine or not .I purchased a pack (100) of Taiyo Yudan discs ,as they were reccomended to me .and since I have become aware that there are counterfiet disc being sold , as I want to use these discs largly for archiving photo,s I dont want to use an inferior copy .
I have looked at the packaging and the discs , the packaging has Taiyo Yudan DVD-R47 label ,also the inner packaging has made in Japan sticker .
in the coloured portion of the disc very close to the clear area at the centre are the letters GH000915 , opposite in the same section is 0809(smaller)
in the clear plastic area , I can just make out AK821B702668GH
They were purchased from CVB Media ltd and have an (approved Tanio yudan verified japanese source) sticker on too.
any way to be sure.
