Since our formation we have specialised in the supply of cd r
discs and dvd discs, cd duplication equipment and services.
We continually monitor the market to ensure that we are offering the very best
quality discs and the most up to date, efficient and reliable duplication and
printing systems.

cd r discs
A cd r discs disk contains a long string of pits written down on the cd duplication
disk. The edges of the pits correspond to binary. Each pit is approximately
4 microns long. Each track is separated from the next track by 4 microns.
Pits are formed in the polycarbonate cd duplication by an injection molding
process. As such, they represent some of the smallest mechanically fabricated
objects made by humans. The width of a cd r discs pit is approximately the wavelength
of green light. The tracks are separated by approximately three times the cd
r discs wavelength of green light. Diffraction from these cd r discs is what
gives cd r discs disks their beautiful cd r discs colors.
cd duplication
When the metal is thick enough the metal layer is separated from the glass
master. This results in a metal negative impression of the cd duplication disk.The
electroplating process is then repeated on the father. This typically generates
3-6 positive metal impressions from the father before the quality of the father
degrades unacceptably. These impressions are called alfred.
The electroplating process is repeated again on the cd duplication. Each cd
duplication typically makes 3-6 negative metal impressions called sons or stampers.

Once the cd printers are molded, a metal layer is used to coat the disks. Aluminum,
gold, copper and silver are all reflective enough to be optically acceptable.
Gold is typically too expensive for cd printers and copper has a peculiar appearance.
Thus, aluminum and silver are the most commonly used cd printers metals.

sons are suitable as molds for injection molding.
Following metal cd printers deposition, a thin plastic layer is spin-coated
on over the metal. This can be a nitrocellulose layer suitable for air drying,
or an acrylic plastic that is cured in cd replication.

An additional thin layer of polymer covers the metal. Finally, a label is silk-screened
on the top. The cd duplicators pits are far closer to the silk screened side
of the disk than they are to the read-side of the disk Thus, it is easier to
permanently damage a disk by scratching the top.

Each pit is approximately 4 microns long. Each track is separated from the
next track by 4 micro.The fabrication of a dvd recorder disk is a fascinating
process. This process is discussed in some detail in the dvd recorder disk is
a r disk of polycarbonate. The center contains a hole 17mm diameter dvd recorder.The
electroplating process is repeated again on the dvd duplicators.

To do this, a glass plate about 260 mm in diameter is lapped flat and polished.
The dvd recorder plate is coated with photoresist. A mastering tape is made
containing the information to be written on the disk. A laser then writes the
pattern from the master tape into the dvd recorder. Laser light incident on
the polycarbonate dvd duplicators will be refracted at a greater angle into
the surface. Thus, the original incident spot of around 4 micrrns will be focused
down to about 1.7 microns . This is a major win, as it minimizes the effects
of dust and scratches on the surface of the dvd duplicators.
