JVC is the brand that Taiyo Yuden uses in the US. They have their own brand, That's for Japan and a few other countries, including Greece for some reason. If you are in the US, you can get unbranded Taiyo Yuden from rima.com, supermediastore.com and meritline.com among other spots.
Sony used to be one of my recommendations for blank media, as their quality was quite good. They manufactured some of their own, and had Daxon making some using their mid codes. Now days, Sony is no different from the other brands, using mid grade CMC or Ritek made disks. TDK has stopped making their own, and also buy from the same sources. CMC, Ritek, and MBI seem to have taken over most of the market.
The reason you don't get much info on these middle grade disks is that they are inconsistent in quality and not always the same disks under the same brand. You don't know what you're going to get, and even if you get the same mid code, they may not burn with the same characteristics in your drives.
Best cdr's are Taiyo Yuden. Also found at rima, supermediastore and other online shops. You used to be able to buy them locally under the Maxell Pro cd brands, but no longer. Many people like Ritek cds also, but I'm not up to date on which brands they can be found under.
