The eBay seller silver-tek_media_store is selling fake Taiyo Yuden blank disc with the disclaimer: This media is not made directly by Taiyo Yuden, in fact this media is made by a 3rd party manufacturer who has paid royalty rights to Taiyo Yuden to use their media id codes. In order to do this the discs must meet or exceed Taiyo Yuden specifications for reliability, compatibility, and craftsmanship, or we would not be allowed to use their media id code or use the Taiyo Yuden name.

After emailing Chika Nakasutka from Taiyo Yuden USA about the matter, this was the response:
Taiyo Yuden is NOT currently licensing anyone to use our media code. We know there are so many counterfeit discs.

That is enough proof that what silver-tek_media_store is selling are Taiyo Yuden (TYG02) fakes.

Check some of the feeback left to that seller where ppl like me knew the truth after having a lot of coasters few weeks after the purchase. After investigation about possible fake media in reputable forums like cdfreaks.com we found the mentioned seller a fraud.
