TABLE OF CONTENTS
The Disc Inspection GuideBefore using your Disc Go Pod, we always recom
mend that you have a quick look at the CDs or DVDs
you want to have repaired. The following is an expla
nation as to why scratches are found on CDs or DVDs,
and the construction of a Disc.
Why do scratches appear on my Discs?
Although CDs and DVDs are extremely durable and
convenient to use, they can easily be damaged
through use on various players and abuse. You may
be surprised by the amount of scratches found on
your CD or DVD collection; this is generally caused by
no fault of the user. Common culprits are cheap CD or
DVD players, in car CD auto changers, poorly
designed CD cases; the list goes on and on.
Although your CD or DVD may still be playable, the
player is probably having a hard time decoding the
sound, image or data if the play surface of your disc
is covered in scuffs and scratches. This generally leads
to the CD sounding a little dull and lifeless or skipping
and stuttering.
If you remove the scratches from the surface of the
disc, you allow your CD or DVD player to get on with
decoding all the information without having to do
numerous error correction procedures, which allows
the music or video to flow.
It’s a bit like looking at your image through one of
those distorted mirrors at a fun fair, luckily for you, CD
and DVD players are built to compensate for this, but
the downside is that it often causes the detail of an
image or sound to become muddled.
How are CDs made? A Disc is made up of four layers. The first layer is the
thickest and easiest to repair. However, the other three
layers combined (reflective foil, lacquer, and graphic)
are only as thin as a human hair and offer little or no
protection of the data beneath them. You can see
the different layers as shown in Fig 1. Disc Layers.
Polycarbonate Plastic Disc (first layer)
First, data is
stamped on the
topside of a plastic
disc creating mil
lions of “on’s” and
“off’s” or zeros and
ones. On record
able CDs, data
can be burned in
at different levels
within the plastic
disc, for multi ses
sion recording.
Please note that
recordable CDs
have a much thin
ner layer due to
the manufacturers
name printed on
this layer.
Reflective Foil Layer (second layer)
Second, a micro thin layer of aluminium (copper, silver
or gold on higher quality CDs) is applied to the top of
the CD covering the data. This layer reflects the laser
beam back through the plastic disc, allowing the
stamped data to be read.

Lacquer Layer (third layer)
Third, lacquer is dripped onto the disc and spun at a
high speed to create a thin layer of sealant for the foil
layer. This seals in the foil layer, but offers little or no
protection for the foil or the data beneath.
Graphic Layer (fourth layer)
Finally, a layer of ink is screened onto the lacquer
layer for dynamic graphic and/or sales impact.
(Recordable CDs don’t have this layer.)
How Can You Repair Your Discs?Compact Discs are made of Polycarbonate plastics
(just like plastic lenses in sunglasses) and are manufac
tured through a moulding process that makes the disc
perfectly flat. This perfectly flat surface allows the laser
beam to go straight up and reflect back off the Foil
Layer and retrieve the Digital Information that has
been stamped into the topside. The stamped informa
tion is called Pits and Lands or 0’s & 1’s and this is what
the Laser Beam brings back to the Decoder.
A scratch, finger print or some foreign object that
blocks or breaks up the path of the laser beam (Fig. 2)
will cause the disc to either skip or freeze up depend
ing on which disc format you are using at that time.
Remember the laser beam reads the digital informa
tion from the centre of the disc to the outer edge in a
spiral manner.
With DVD Audio
and Video media,
Sony PlayStation
2™, X Box ™ and
Sega Dreamcast™,
the digital informa
tion that has been
stamped is now
going to the outer
edge of the discs.
This means that if
you don’t repair
your damaged
discs with Disc Go Pod Technology, then there is a
good chance that the other disc repair technologies
will round the edges of your disc during their repair
process. The laser beam will then follow the curve cre
ated by their process and you could lose the last track
on those discs.
How can I tell if my disc is inneed of treatment?If the CD or DVD has started to make funny noises, or
skips and stutters when you listen or watch it, then the
chances are that the CD or DVD has scratches on it.
If you are servicing the rental or retail market, such as
used video games, it may be desirable to repair any
disc with surface damage. This will suggest to the cus
tomer that this disc is in “new” condition, and may
fetch higher resale prices.
Identify if the disc can be fixed.
Cracks Inspect the disc first for any cracks on the
disc. Typically, discs will start to split from the inside ring,
and work towards the outer edge. Give the disc a
very slight bend to see the cracks more clearly.
Occasionally, cracks will start from the outer edge, or
may be located in the centre of the reading area. If
any crack is found, the disc cannot be repaired.
Dents Dents are large indentations on either side of
the disc. Dents will sometimes appear to be deep
scratches; however they have caused irreversible
damage to the disc which cannot be repaired. Dents
are caused by some sort of blunt force to the disc,
such as being stepped on, being bitten by a dog, or
placing heavy sharp objects onto the disc. Dents can
sometimes be seen protruding through the other side
of the disc.
Warping Warping is when the disc, which should be
perfectly flat, has been bent or warped due to heat
damage. This type of damage will typically be seen
around the entire edge of the disc and can be seen
in the reflection of the disc. To inspect for warp dam
age, look at the reflection in the mirror side of the disc.
Reflect a straight edge, such as a fluorescent light
tube in the ceiling and tilt the disc back and forth
while looking at the reflection of the light in the disc. If
the light tube appears to be distorted, the disc may
be warped. Warp damage can occur due to leaving
the disc in sunlight, or cheap repair methods.

Figure 2 - Scratch Deflection
If the disc is damaged in any way described above,
the disc cannot be repaired.
Identify the type of disc
CD or DVD? There are types of damage that can
occur on one type of disc, which will not occur on the
other. To identify the type of disc, look at the label side
of the disc and locate the identifying mark.
Inspect for specific damage
CD Damage Foil Damage Foil damage occurs
when the label side of the disc has been scratched.
Severe foil damage can be seen by holding the disc
up to a strong light source. If light can be seen through
the scratches in the disc, the disc has been severely
foil damaged. Light foil damage can also prevent the
disc from playing, but it is much harder to locate. One
easy way to see light foil damage is to first inspect the
label side for any type of scratch in the graphics or sil
ver top. If a scratch is located on the top side, view
the bottom side to see if the same scratch appears to
the optical side. If the disc is dark, such as a
Playstation or PS2 CD, assume the disc is damaged.
One other method of viewing foil damage is to look
at the scratches on the optical side of the disc. If you
can see a reflection of the scratch in the mirror of the
disc, the disc can be repaired. If you cannot see a
reflection of the scratch, the scratch is likely to be foil
damage on the top side. See figure 3 for an example
of foil damage.
Determining Which Side Is
Scratched
The Reflection Test
• Hold your CD or DVD disc, with the bottom or play
side up.
• While looking at the scratches on the play side, tilt
the disc slightly, back and forth,
• Now check each scratch for a reflection or double
appearance.
• Scratches on the bottom of the disc will have a
reflection.
DVD Damage Layer Separation A DVD is similar to
a CD, however it is like having two CD’s with the label
sides placed together and glued. This is perfect for
protecting the information from foil damage, as the
important layers are on the inside of the disc, instead
of the top. However, there are sometimes problems
with the two glued discs pulling apart. When these two
discs separate, it will damage the foil on the inside of
the disc. This type of damage is relatively rare, and is
usually caused by excessive heat and/or severe
bending. Inspect the gold or silver side of the disc, if
the consistency of the gold or silver color seems to
change from the inside ring to the outer edge, the
disc may have separation. Give the disc a slight bend,
if the color changes in a concentric pattern, the disc
has layer separation.

Scratch Damage
If the disc passes the above tests, it is probably scratch
damaged. Scratch damage is the largest type of
damage in discs and will typically result in 94% of all
disc failures. Scratch damage can be repaired. Use
one of Disc Go Tech’s quality machines to remove the
damage, and leave the disc looking as good as new!
Scratch Damage LevelsThe level of scratch damage can be difficult to deter
mine. Some discs may have scratches covering the
surface of the disc, but the scratches may not be very
deep. Other discs may look great, except for one
large scratch. Damage levels are determined by the
depth of the scratch, not the number of scratches. The
deeper the scratch, the longer it will take to be
removed. Please refer to the pictures below for some
typical examples of light, medium and heavy scratch
damage.
Light Damage (5 min)
Light damage is characterized by small, hairline type
scratches. It can also contain light scuffs, marks and
debris such as food or glue residue. This type of dam
age cannot be felt when running your finger across
scratches.
Medium Damage (10 min)
Medium damage is typically larger scratches than
those in the light category. Medium scratched can be
felt when running your fingernail across the scratch.
You should be able to feel the scratch, but your nail
should not stop at the scratch. More extensively dam
aged discs with many scratches on the disc will typi
cally have one or two scratches that would fall into
the Medium damage level. These discs will need to be
run through a medium cycle.
Heavy Damage (15 min)
Heavy damage is the deep knife or screwdriver type
of damage. This type of damage can be felt when
you run your fingernail over the scratch and it stops in
the scratch. This type of damage can be very severe.
Occasionally it may be necessary to run a disc
through a heavy cycle twice. If the disc has been run
through twice, and the damage is still present, it is rec
ommended that this disc be deemed “un repairable”.

4. Preparing for Disc Repair
A. At the back of the unit, ensure that the polish tube
is in the center of the flow valve. Turn the screw on
the flow valve until thepolishing tube is pinched
slightly.
B. If not already closed, close the lid until it snaps into
place.
C. Loosen the two white polishing wheel knobs on the
lid by turning them counter clockwise until the pol
ishing pads inside the unit no longer press onto the
disc.
5. Repairing the Disc
A. Agitate the chemical in the tank with a small stick
through the hole in the tank lid.
B. Plug the unit into an electrical outlet and press the
start/stop button. The red power indicator will flash,
showing you that the unit is in operation.
C. Look through the viewing window and ensure that
the polish is covering the disc.
D. Adjust the pressure of the polishing wheels by turn
ing the wheel knobs clockwise until the green cen
ter pin of the polishing wheels begin to spin. Slowly
continue to adjust the pressure until the pin begins
to slow down, back off pressure slightly until the pin
resumes full speed of rotation. Note: When in oper
ation it is normal for the unit to quietly vibrate. If a
louder vibration occurs, ensure the polishing wheel
knobs on top of the unit are adjusted as described
in this step.
E. Allow the unit to complete the cleaning process.
The unit will turn off automatically after five minutes.
The red power indicator will stop flashing when the
operation is complete.
6. Removing the Disc
A. Release the lid by pulling the release catch down
and towards you.
B. Check to confirm that the disc damage has been
repaired. If any disc damage remains, close the lid
and repeat the cycle by pressing the start/stop but
ton. Refer to the Disc Go Tech Disc Repair Guide
included in your shipment for information on dam
age levels and treatment.
C. Unscrew and remove the white disc clamping knob
by turning it counter clockwise while holding the
disc steady.
D. Remove the disc and place on a Disc Go Tech
Micro Fiber Cloth and pat gently (do not rub) to
remove repairing solution.
E. Spray both sides of disc with 1 2 mists of Disc Go
Tech Disc Cleaning Final Spray and gently wipe it
with a Disc Go Tech Micro Fiber Finishing Cloth until
disc is dry and shiny. This completes the disc repair
operation. To repair additional discs, simply repeat
steps 3 6.
Note: Top up polish tank with water every 4 5 repairs.
7. Cleaning and Maintenance
Like any tool or piece of machinery it is a good idea
to keep your Disc Go Pod clean. This ensures good
quality repairs and helps to ensure the motor does not
seize because of build up of polish inside the machine.
At the end of repairing your set of discs for the day we
recommend cleaning the machine using the following
steps:
A. If you have not already done so, unplug the unit.
Open the lid on the polish tank at the back of the
unit and dispose or reserve the disc repair solution
for later use.
B. Fill the polish tank with water, ensuring the pump is
covered with water and close the lid.
C. Plug in the unit and press the start/stop button to
run and rinse the machine for 60 90 seconds and
then press the start/stop button to stop the
machine. Unplug the unit.
D. At the back of the unit, open the polish tank, dis
7
card the water and close the lid.
E. Open the lid on the top of the repair unit. Pulling on
the center spindle, remove the rotation table
together with the black repair cushion from the
center of the repair unit.
F. Wipe the inside of the unit clean with a damp cloth.
G. Clean the rotation table and disc cushion with a
damp cloth. The disc cushion will retain a whitish
color from the disc solution; this is normal and will
not affect the operation of the unit.
H. Reinstall the rotation table and cushion. Replace
the white disc clamping knob by turning it clock
wise. Close the lid.
