FOR TY cd's use the following link. http://www.cdr-info.de/index_cdrohlinge.php
Now choose TY as Hersteller. And you will see quite some different disc's by TY.
However do remind that some compannies also use other manufacturers as TY. So check also if the box says made in Japan to be shure.
(Okay you got me since sometimes made in Japan can mean made in Japan by Kodak Japan but then again these are also very good disc's and Kodak doesn't make cd-r's any more so that change is very small. Also for Emtec disc's look if it states TY then you really know if it are Taiyo Yuden disc's))
Also the small B-brand Taibo Tech is made by TY.
