Lense cleaning disk, or if you're tech savvy and can open up your console(DON'T TRY IF YOU'RE NOT) then you can always replace the lens yourself. They're really cheap online, you could even just purchase a new disk drive for your console.
Gamertag - GotMyProSocksOn What you think is broken when it comes to a game could easily be explained with you being terrible at it. Halo > Call of Duky.
cut a cereal box to fit the disk drive and slide the cardboard into the top of the tray while the tray is closed
the other is to knock on top of the xbox (like knocking on a door) when inserting a disk and closing the drive
Those would not help at all, in fact they would probably make it worse. An Xbox that isn't reading discs may still read them occasionally fooling people to think that their incredibly weird strategies work. The only things that would work is cleaning the lens or adjusting the laser strength.
