Out of business for awhile now.. I'd guess 90% or more CD-Rs made now are CMC. Ritek might still make some. There is also falconrak in UAE making them. At this point I am curious if anyone in Japan is still doing it... Does Memory-Tech in japan make recordable media??
To be clear, Taiyo Yuden sold their patents and manuf equipment to CMC Magnetics in Taiwan.
Taiyo Yuden sold their process and tooling to CMC, and they're now sold as "CMC Pro" discs. I previously used JVC branded Japanese Taiyo Yuden discs. I switched to CMC Pro when I ran out, and haven't noticed any difference in quality.
