Where can you buy blamk gamecube media from?

Also what do you need to copy disks?
Dvd burner or standard burner?

Yes I do know the cube hasnt been cracked yet but I just want to try some stuff out.

1) You can't. You can however buy mini DVD-R's.
2) You can't. You can however write to mini DVD-R's with a DVD-R burner such as the Pioner A03/103 & A04/104. You can't however read the GC disc to write it, so what is the point??

There are also mini CDR's that hold around 180mb.
