To quote Kerry:
Taiyo Yuden is only made in Japan. […] TY Verbatim is primarily showing up in Europe these days.
They’d be Made in Japan. That’s the easiest way to identify the discs as made by TY; every 8x and 16x Verbatim disc made in Japan that can be found nowadays is TY.
However, due to your geographical location [the U.S.], you probably won’t see Verbatim-branded TY. Also, [I]for 16x Verbatim DVD media[/I] the actual MCC/MKM disc models are preferred over the Taiyo Yuden disc models by a large part of the CD Freaks population, so I wouldn’t worry about not getting TY media.
