Chances are good that these discs are manufactured by Taiyo Yuden.
But keep in mind that these are the Maxell
Audio CD-Rs (I've seen this same blank media in Sam's, Costco, and other places). If you want Taiyo Yuden-manufactured Maxell CD-Rs that are not tailored for a stand-alone audio CD recorder, then you'll need to get the Maxell CD-R
Pro.
