### Examples of error correction

Badly scratched medium. This medium has been carried around without protection in a backpack; the round prints were made by a bottle of water. The scratches are a bit exaggerated due to reflections from the photoflash.

A surface scan of the medium yields about 135.000 unreadable sectors (of 2.200.000 total, giving about 6% defective sectors). During the recovery of the medium image (using standard settings) a maximum of 22 errors per ECC block is counted which equals to a 69% load of the error correction under the applied settings.

Why PI/PO scans won't suffice...
