How Do You Fix a Laser Burned Xbox 360 Disc?

I've tried toothpaste, I bought this thing that repairs disc scratches and then cleans it. How do I fix this? Nothing I try works. Help!

Suggestion:

You can't it's impossible you can go return the disc if you still have reciept or anything. Sorry but that disc is gone

I heard Gamestop repairs disc. Might as well call them and check with them.
