But if you used the same Brand DVD Blanks for other Backup procedures you should rerecord them all right away before they start doing the same thing.
If you really are desperate and [b]Money is No Object[/b] you can take this Separating DVD to a Data Recovery House like On Track and let them loose with it, but I doubt that there is anything that is possible to do here as the dye layer has been damaged though they may be able to recover some Data off it.
[b]Important[/b] Do Not place this Disc into any DVD Reader as it may denigrate and destroy the Drive but far more importantly injure anyone near the drive when it falls to bits. Todays High Speed DVD Readers are not suitable to read things like this you need to place them in a slow speed drive where you can limit the speed and at the same time force the layers back together. This is a special machine that isn't a Computer or any Domestic DVD Drive. Ideally disc's like this need to be read at less than 100th speed so there is no chance of them breaking up.
