The problem is usually due to a poorly written disc, typically one with
excessive errors. You can confirm that by measuring write quality with a
program such as Ahead's CDSpeed or Arrowkey's CD/DVD Diagnostic.

If that's the problem, there's not much to be done to recover the data.
Tools such as CD/DVD Diagnostic will read the disc as well as possible,
but you'll be left to put the sectors together and to correct the errors
by hand - not a task to be taken lightly.

If the disc is poorly written, you should look to find a better match of
medium with speed and writer. That won't help with existing discs, however.
