F.A.Q - Frequently Asked Questions

Odrazka   Why do some DVDs cost more to repair?
Some DVDs are double sided and have to be repaired on both sides for which some disc repair services may charge more.


Odrazka   Can every scratched CD be repaired?
There is good news and bad news here. The bad news is that if a scratched CD has damage to the data layer itself there is nothing that can be done to retrieve this data. The data layer is very close to the label side of the disc and so is vulnerable to scratches from the top. To see if the data layer is damaged, hold the disc label side toward you about 20cm from a light bulb. Any pin-pricks of light that show through indicate damage to the data layer. The good news is that discs with minor damage to the data layer often play perfectly after restoration. Naturally, the worse the damage, the less likely it is that the disc can be restored. Most of the companies that offer CD repair will give you a free assessment of whether it is worth repairing the scratches in the CD.


Odrazka   What CD repair machines do TDR use for their repair service?
Most of the repair services operated by the TDR network use the Star Disc CD repair machines which guarantee the highest quality repairs, perfect flatness and perfect edge definition. Recently, in addition, some have begun using the DGM6 CD repair machine with equally impressive results.


Odrazka   How do you fix scratched discs?
Using tried and tested, patented technology we gently polish away a very small layer from the bottom surface, just sufficient to remove any scratches. We then restore it to a mirror finish. This allows the light from the laser to pass cleanly through the disc to the data layer and back to the laser again.


Odrazka   How many times can a disc be repaired?
Naturally this depends how deeply scratched the CD is each time, but we conservatively estimate a minimum of ten times, far in excess of what most discs will experience during their lifetime.


Odrazka   What kind of damage cannot be repaired?
Warped or broken discs cannot be repaired. Data that is lost due to damage to the foil data layer cannot be replaced although minor damage often does not prevent a scratched audio CD playing back perfectly after repair.


Odrazka   Why won't my disc play any more?
Put simply, the reason most discs won't play is because the bottom (non-label) surface is scratched. This bounces around the light from the laser that reads the data in the disc. This makes it hard for the player to know where to go next, which is why it either jumps around or gets stuck playing the same section.


Odrazka   Is it safe?
Completely. All the machines and processes we use are tried, tested and patented.
