Not sure, but I always thought the cdrs made from taiwan were considered crap.
For example, Imations made in us and japan were considered good to excellant, but the ones made in taiwan were generally crap.
TDKs from taiwan were considered crap, the good ones were either from TDK japan or TY.
Fujifilms used to be made in taiwan and got low ratings. Now they are made by TY and considered good.
TY, kodak gold and Mitsui are are considered excellant and made in Japan.
I may be wrong, but I can remember 1 manufacturer (not brand) of CDr from taiwan that was considered good or excellant. I know Taiwan is responsible for a lot of the electronics in the world (memory, graphics etc etc.) but their track record for CDRs is spotty at best.
