Yes — almost all optical discs, including CDs, DVDs, Blu-rays and game discs, can be repaired using a professional disc repair machine, because they share a similar polycarbonate playing surface.

Repairable formats include music and data CDs, DVDs (films and recordings), Blu-ray discs, and game discs for PlayStation, Xbox, Wii, and even older formats like GameCube (with an adapter).

Disc repair machines remove a very fine layer of the disc’s surface (micron by micron) and then polish it back to a smooth, mirror-like finish. Most discs are fixed in 1–2 minutes.

No - only scratches on the underside (playing surface) can be repaired. Damage to the top side of the disc (label/artwork side) cannot be fixed with these machines.

There are three main benefits:

• Restoring discs that don’t play anymore (e.g. old family recordings)

• Maintaining and protecting your collection’s condition and value

• Repairing discs to resell them for profit.

They’re used by individuals, collectors, libraries, second-hand stores and resellers — basically anyone who wants discs to look and play like new again. But there's a growing number of people repairing and selling discs for financial purposes.
