Ritek is the company that manufactures the discs for Office Depot so I would say "Yes"! These are what I use on my Gamecube exclusively.
If you get a spindle that is 4x, these are actually Ritek G04s. If you get a spindle that is 8x, these are even better! These are actually Ritek G05s. Every time Office Depot has a sale on these, I'm all over it.
