Game error this disc is unreadable keeps coming up when trying to load games tried cleaning disc with a soft cloth but it is happening with all games

Either the game no longer works and to buy a new one or you need to replace your dvd drive.

If you get the error with just one game, but not others, unfortunately it is likely damage to the disc. If it is under warranty, or if you bought it at a return-friendly place, maybe you can get a replacement. If the system is giving you this error with several games, it is likely the disc reader in your Xbox. The Xbox 360 has a well-known issue with DVD drive failure over time. If your system is still under warranty, or sometimes even if not (because this was such a big problem for Xbox), Microsoft may repair it. Try calling them and patiently discussing it. If it is not under warranty, and you are good with repair work, try this: http://hardandsoftgaming.wordpress.com/2011/03/12/replacing-a-faulty-xbox-360-dvd-drive-firmware-flash-or-circuit-board-transplant/

1. Some games may need to be cleaned. Clean each disc with a soft, slightly damp cotton cloth (use water only). Clean them from center towards the edges; do not use a circular motion. DO NOT use paper. Once they are cleaned, dry the disc using a dry portion of the cloth and wiping in the same style as you did to clean the discs. After all of the water is gone, let the discs sit for at least two minutes to completely dry before inserting any of them into the Nintendo GameCube.
   
2. Check for Unlicensed products. Make sure that you're using only licensed products with your Nintendo system. Unlicensed products are not tested for compatibilty and may not work correctly with all games. Try playing the game without the unlicensed accessory.
   
3. Ensure the games are being loaded properly. With the power turned off on the system, replace a Game Disc (printed side up) in the system, press down gently on the Game Disc until it locks on the center hub. Close the Disc Cover and press the power button ON to see if the game comes on the screen. Try this with a few of your games.
   

If Troubleshooting doesn't fix the problem, and it is happening with all your games, then your system will need repair. Check out our convenient repair options.

No Game Disc:
This error can occur when the Game Disc has been removed while the system is on and then the Disc Cover is closed. Follow these troubleshooting steps:

1. Ensure the game is inserted correctly. With the power turned off on the system, replace the Game Disc in the system, printed side up. Press down gently on the Game Disc until it locks on the center hub. Close the Disc Cover and press the power button ON to see if the game comes on the screen.
   
2. Determine if this happens with more than one game by inserting a different game into the system.
   

If the error occurs with all games, follow the Multiple Game Disc troubleshooting.
If the error occurs with only one game, follow the individual game disc troubleshooting.

Are you under warranty? Eventually your drive is going to fail. This is usually the first sign assuming your disc is fine.

check the disc for visible scratch,use a soft cloth to clean the disc,after cleaning the game disc see if the error will be the same
try using a different game disc,see if the issue will be the same if it is,please do contact xbox for the lens of the disc console

dirty lens or disc

check around the disk tray for dust and use a vaccum cleaner to clean it, then use a wet cd lens cleaner with cleaning fluid a few time.
This should cure the problem but it might be that your drive is on its way out

One problem... The Disc Is Unreadable... clean it with a soft cloth, then insert it, if still same problem... take it back from where you bought it, and tell them the problem, they should replace the Game.

dvd drive is damaged tri taking it apart and clean the laser eye

yes you can theres two ways,

you can buy a disc cleaner thats just a normal disc with brushes on it, and it wil spin inside and clean the lense.

or you can take it apart and manually clean the lense

problem solved :)
