True. The best TDK cdrs are probably made by TDK itself. The Certified Plus.
However, it has been shown over and over again that TDK has outsourced more than one manufacturer/factory to make their "entry level quality" 100pk spindles of the 100% Certified cdrs. The majority seem to be made by Ritek (not that good) and others are made by Taiyo Yuden which have a much better reputation.
Actually, top TY stuff is right there with anything out there.
However, I have a sneaking suspicion from anecdotal evidence that the TY made 100pk spindle of 100% Certified cdrs are probably "second quality" Taiyo Yudens - which in turn are still better than Ritek stuff. But that's just my opinion. I mean, why would Taiyo Yuden put their best effort into making 100pk spindles of TDK entry level cdrs and undercut their own products under other brand names? Especially for a spindle that you can get for some 16 dollars right now at Onvia?
That doesn't make sense to me or to anyone who has a marketing/economics background (like I do)
