I’m speaking of Japan, BTW. I saw in a store in Akihabara yesterday, per 10 discs: TY DVD-RAM=2240 yen, Mitsubishi DVD-RAM=1295 yen, Victor DVD-RAM=995 yen. All three packaging indicated ‘Made in Japan’.
I tried the Mitsus and the discs are plain white on top. Backside has the same copper color and pattern like my TYs. TYs I guess?
