No. I seriously hope that you do not dream that Ritek were the only manufacturer who produces discs of different quality, and sells those different qualities under different names and different prices
I think you're confused! I know all about different brands have different manufacturers. I am referring to FUJI YUDEN000T02 and your branded Plextor is made by the same manufacturer which is TAIYO YUDEN. You seem to think just because your discs are branded Plextor it would be better discs. I beg to differ when they are both made by TAIYO YUDEN.
