Well today I bought a 100 pack (cake) for CAN$27 from Canada Computers. Apparently the result is impressive, regardless of whether it is fake or not, under my Benq 164W (1640 external) burned at 8x... Last month I spent CAN$60 on a TYG03 100 pack from another local computer store. It should be real because I saw their stock inventory with boxes originated from Japan. The shrink wrap also shows "Taiyo-Yuden DVD-R16x" with a barcode sticker and an information sheet (in Japanese) inside.
Now I can't say if the current TYG02 from Canada Computers is genuine. No information on the shrink wrap, no barcode sticker and no information sheets. But the case seems to be identical to the one from the other local store. Nero test attached.
P.S. This price still makes me confused. It could also be a very high quality inferior (therefore no name). I wonder how much is an 100-pack TYG02 in Japan?
