Wii games burning iso to disc

I'm trying to find out what kind of disc I need to use. I just bought a wii-u and want to play some of the games that I have the .isos for on my computer on the actual system. Do I need a CD, a DVD, or some other kind of disc? That's my main question here.

DVD R (NOT RW). Your wii must also have a modchip.

Thank you I had the actual disc a while ago but lost it so it is nice not to have to spend another $50 on replacing it.
