TDK Europe does not indicate the country of origin on the packaging anymore
I still have a 4x DVD+RW with "Made in Taiwan" on it, in the old design, but most old design packages of the Speed-X/8x DVD generation didn't have a country of origin anymore.
The photo does not look like a TY cakebox at all. Judging at that photo, I think it could be MBI or TDK Luxembourg made. The Luxembourg-made cakeboxes have a five-letter code looking like BWAEB or something similar above the recycling sign on the base, usually have a gray spacer foam ring and a smaller "Lock/Open" writing than the MBI cakeboxes have.
Since the spacer is gray and not white, I think it is TDK Luxembourg made with TDK's own code - very good media.
That's is TY's own media brand, and media packed directly at TY's plant in Fukushima is packaged in a special cakebox form, which doesn't look like the cakebox above, but more like this:
If you can find TDK 16x DVD+R media, currently there are some YUDEN000 T03s around, in 25 and 50 pcs That's cakeboxes. Not all shops will have them, many still have old TDK-code 16x +R stock made by CMC.
