If you want to repair your scratched discs, then it is really important to understand what type of damage can and can not be repaired. The last thing we want to do is tell you we can’t repair your disc after you have gone to the trouble of posting it to us! The purpose of this post is to explain how to check your discs for unrepairable damage.

Our industry-leading disc repair machines are incredibly effective at removing all manner of scratches from the polycarbonate layer of your disc (including Xbox 360 Laser Burn), but they can’t fix the following types of unrepairable damage;

Foil Damage

Foil damage is the most common type of damage we see on a disc. It typically occurs in one of two ways. Firstly, a scratch on the disc can be so deep that it actually penetrates the data layer – you would really have to go to town on the disc to damage it to this extent though. The second way is more common and occurs when the printed side of the disc is damaged. This is because the discs data is actually stored right under the printed side, making it far more vulnerable to irreversible damage than the polycarbonate which is designed to take at least some punishment! The easiest way to check for foil damage is to hold your disc up a strong light. If you can see light through the disc, then the data layer has been damaged and the disc cannot be repaired.


Some cases, particularly DVD ones, are manufactured in such a way that discs can suffer cracks in the centre of the spindle when they are removed. If the crack reaches the playing surface of the disc then it not play and it can not be repaired because the crack corrupts the data layer, rendering it unreadable. If the crack doesn’t reach the playing surface then we should backup the disc as soon as possible.


These occur as a result of a strong impact against the disc, usually when discs have been stored out of their cases for extended periods of time. They are fairly easy to spot, appearing as a deep crease across the disc. They cannot be repaired as they penetrate the data layer, making it unreadable.


It is important to store your discs properly. If you leave them near to a heat source such as a radiator, or out of their cases exposed to the sun then they may warp or bend over time. This results in the disc becoming unplayable as it alters the angle at which the laser reads the data. We are unable to reverse the warping process and you will need to replace your disc.

If your disc suffers from any of of the faults listed above then please do not send it to us as it can not be repaired. If you need any help or advice on how to check for the damage listed above, then please contact us.
