What's the relation between Mitsui and Yamaha?

I was going to buy my Mitsui CD’s found @ pricewatch as “mitsui gold” and there came Mitsui DVD’s and Mitsui Cd-R’s as “Yamaha” manufacture…

Is that right, can i buy those and they are good, or i should go with kodak?

Thank you!

(please, try to hurry in the answer)
