How it works...
Repairing a scratched disc is a simple case of removing the scratches so you are left with a smooth, mirrored surface.
Some people suggest you can do this by hand, but it is significantly quicker, easier and more effective to use a professional solution to restore your discs to almost perfect condition.
There are a few facts that are important to know when considering getting your discs repaired:
What goes wrong?
A disc usually skips because its surface is scratched and the laser cannot read its data correctly. This information usually remains intact as it is protected within the disc.
Is it the end?
Almost all scratched discs can be repaired, which accounts for about 95%. But cracks and top surface damage can not be fixed as they cause irreparable damage to the data layer.
What if it happens again?
Most discs are 1.2mm thick and scratches are often just a few microns deep (1 micron = 0.001mm), meaning the same disc can be repaired many, many times.
What about my Blu-ray?
All disc formats can be repaired, though some formats like Blu-ray need special treatment and cannot be repaired quite as many times as a DVD.
