Having a disc professionally polished can allow the laser beam to correctly pass though and read the data. Scratches on the bottom polycarbonate layer can obscure or deflect the laser beam and it unable to correctly read the lands and pits on the write layer. The good news is that optical discs are read from the inside out, so you may be able to recover some data. The glue has degraded and released, that portion of the disc, in a circle is gone. If the disc has a rainbow / kaleidoscope effect starting from the edge of the disc. If there are light splotches under the bottom polycarbonate layer, the glue as degraded and that area of the disc is unreadable. There was probably a buffer underrun during the burn, resulting in an unreliable, possibly unreadable discs. If there are rings like Saturn, even if they're the same color, it's likely a bad burn. ![]() When looking at the bottom of the disc, the burned section should be a single continuous purple/blue color. Depending on the file size, it may be the entire file(s). Unlike a linear scratch which may affect only a tiny portion of the file, a radial scratch likely makes the track(s) under it unreadable. If the scratch is radial, in a circle around the disc, unless it's very light, that portion of the disc is unreadable.

Even a small address label, remove it with Goo Gone, rubbing alcohol or warm soap and water. You have to buy the program to do the actual recovery. ISOBuster is more powerful, but will only show a tree of files available for recovery. Both will attempt to make an exact copy of the disc. Try ISOPuzzle (free) or ISOBuster (paid).
