| 1. 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. |
| 2. How do you fix this? |
| 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. |
| 3. Does this work for
every disc that won't play? |
| There is good news and bad news here. The bad
news is that if the data layer itself is damaged
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 we regularly
process discs with minor damage to the data layer
that play perfectly after restoration. Naturally,
the worse the damage, the less likely it is that
the disc can be restored. If you wish we will
assess free of charge whether we think a disc is
worth processing. |
| 4. How does MHTC do it? |
| Essentially, we use a very fine polishing
machine to remove the scratch and then restore
the disc's surface to a mirror finish. |
| 5. Is it safe? |
| Completely. The machines we use are tried,
tested and patented. |
| 6. Unfixable? |
| We can't repair warped or broken discs. We
cannot restore data that is lost due to damage to
the foil data layer, although minor damage often
does not prevent the disc playing back perfectly
after repair. We offer a no charge assessment
service for all discs. |
| 7. How many times can a
disc be repaired? |
| Naturally this depends how deeply scratched
the disc is each time, but we conservatively
estimate a minimum of twenty to thirty times, far
in excess of what most discs will experience
during their lifetime. |
| 8. Why do some DVDs cost
more? |
| Some DVDs are double sided and have to be
repaired on both sides for which we charge more. |
