I finally got around to opening a pack of TDK 12X 700MB that I bought from CostCo in early 2001. I burned 3 CD-R's at 12X on both my Lite-On 52X and 48X CD-RW's.
These TDK's are ABSOLUTE garbage!!!!

Eh? I don't know which discs you have tried that are made by Ritek, but they make very good discs. Better than CMC? No doubt, but CMC discs aren't that bad either.

I beg to differ with you. Ritek disks are OK, but, as far as CD media is concerned, they are poor quality. Most people will not have any trouble with Ritek media--but why use Ritek when you can use Taiyo Yuden made discs? TY discs are of much better quality--much better for archival purposes and better for compatibility. But, Ritek discs will satisfy most people's needs. Go to the URL:

There are many sources on the 'net that have pushed me away from Ritek media. CMC Magnetics media is generally of poorer quality than Ritek media. So, just buy TY Made in Japan discs, and avoid Ritek and CMC discs all together.

They were marketed in the U.S. at the time as All Speed Certified Plus.

With respect, that webpage is ancient now. If you take the new type J 40x/48x Ritek media, or the type K 32x cyanine version, you'll find that if you write it at full speed and then read it back with a LiteOn burner and CD-Doctor, these discs give the lowest C1 error rates I've seen other than Taiyo Yuden. I've been getting typically average C1 error rate of 0.2.
With regards longevity, well I have plenty of 5yo Ritek media that's still fine (and still fairly low C1 error levels as well). The ones that have died tend to be the ones I've left on the window-ledge, and I have to say that the TY discs I've done this to have suffered as well (the edges of the discs turn brown etc).
As for Ritek media being variable, all I can say is I've always bought the cheapest Ritek media I can find and with one or two exceptions (probably due to being burned with grade B media etc) I have never had trouble with any of it. And Ritek media is compatible with a range of CD burners which TY isn't. Aopen writers for a start HATE TY.
I also have to say that their results haven't been realised in any case in some examples. They give TDK type 0 (USA! USA! pffft.....) media a higher rating than Verbatim Metal Azo. Well, I have found this to be a load of cr*p. The hallowed dark blue TDK media often develops errors toward the end of the disc after a few years. They don't react well to sunlight or damp conditions and their C1 error count was high in the first place. The Mitsubishi media fares much better (although the printable top surface is garbage.....)
