Taiyo Yuden Verbatim is only available in select European countries. AFAIK, Taiyo Yuden is still strictly a Japan only manufacturing plant.
Here in the U.S., Verbatims may be made in Singapore, Taiwan or most recently India.
All Verbatim discs (except for Taiyo Yuden) will bear a MCC (Mitsubishi Chemical Corporation) code in the I.D. Made in Singapore discs are generally regarded as the "best" Verbatims, but they're becoming increasingly rare. Made In Taiwan discs are now becoming harder to find, with Made In India discs the most common new stock.
Though all Verbatims are supposed to be the same (following MCC's strict guidelines), reports are that the MII discs aren't as good as the MIT, which in turn aren't as good as the MIS! *SIGH* I haven't tried any MII Verbatims yet. I'll stick to MIT until I can't find it anymore.
If anyone is really concerned, follow the link in the OP's post and do a search on the forums. Lots of info there.
Hope this helps.
