| Introduction |
Replication,
the mass manufacture of cd and dvd discs, requires large quantities
to be cost effective and also requires a turnaround time that
is unacceptable to many on-demand applications. Many organizations
and companies choose DVD ROM duplication to effectively distribute
information and content. Compared to replication equipment, DVD ROM duplication equipment is inexpensive and easy to operate.

| Differences between DVD ROM duplication and DVD
Replication |
The typical
DVD purchased at the store is a 'replicated' disc. That means that
it was sent to a plant that created a glass master and then used
that glass master to physically impress the information in the
plastic during the disc manufacturing process.
A duplicated
DVD, though it appears the same to your computer, was fully manufactured
before the information was prepared. The data is recorded to the
disc by laser into a dye that lies above the substrate
(the plastic bottom of the DVD) and the reflector (the
shiny layer that sends the modified laser signal back to the ROM
device). It is fairly easy to tell if a DVD has been duplicated
or replicated, as duplicated DVDs have a colored bottom side,
due to the purple or brown colored dye below the reflector. In
addition, a replicated DVD supports up to 19GB of recorded data,
while a duplicated one has a limit of 4.7 GB per recorded side.

| When to Bring DVD ROM duplication In-House
|
If you are
currently using an outside provider for your DVD ROM duplication services,
you may want to consider doing it yourself. As with all in-sourcing,
this decision should be based on break-even analysis (how soon
will I save the cost of the equipment purchase) and consideration
of your other resources. (Do I have the time/knowledge/desire
to do this myself).
With the advancement
of DVD ROM duplication technology, it is becoming practical for more
and more businesses to bring their DVD ROM duplication in-house. Much
like photocopying paper, DVD ROM duplication can be as simple as simply
placing your master copy and your blank media into the machine
and pressing a button. Some questions your DVD-Duplication specialist
will ask you are: How many DVDs are you doing at a time? How often
are you doing that size of job? Do you need to print on/label
the DVD? Give us a call at 800-646-8881 and we can help you through
the steps.

| Things to Know about DVD ROM duplication
|
| PC-Attach
vs. Standalone |

|
DVD ROM duplication
can be done standalone (without the aid of a computer, like
a photocopier) or PC-Attach (like a network printer). Neither
system has an advantage from a quality standpoint, but their
usefulness differs greatly depending on what the user is
trying to do.
In an
environment where many different discs are being
made, particularly by multiple users, A PC or Network attach
machine makes sense. It enables each job to be created individually
and custom parameters set, including merge fields, individualized
labels, and so on. On the other hand, if many copies of
a single disc are being made, Standalone makes sense.
Standalone removes the idiosyncrasies of computers from
the equation, and is also friendly to novice or untrained
users. Often Churches, Schools, and large-run duplication
houses rely on Standalone duplicators to fill their DVD ROM duplication
needs.

| Recording
Speed |

|
Recording
Speed determines the potential throughput of your DVD ROM duplication
system. The recorders themselves, contained within the system,
record at a maximum speed of up to 52x (CD) or 4x (DVD).
With future technology improvements, it is expected that
the maximum speed of DVD Recorders on the market will increase
in the next year.
Throughput
is generally measured in discs per hour. For example, a
full 4.7 GB DVD being duplicated at 4x takes 15 minutes
to burn. Divide the number of minutes in an hour (60) by
the number of minutes record time (15) and you get 4 discs
per hour. Now multiply that by the number of recorders in
the system, and you will have the output capability of your
DVD ROM duplication system in discs per hour.

| Robotic Types |

|
There
are two types of automated solutions on the market.
Those
that grasp a disc and move it around using a robotic arm
are called pick and place. Benefits of this type of system
include the ability to handle different sizes of media.
Besides the standard 120 mm round disc, many companies'
duplication requirements include the ability to do 'Business
Card' cds, 'mini' cds, or 'hockey rink' cds and other custom
shapes. Templates can be built for some DVD ROM duplication machines
that allow the robotic arm to work with these novelty discs.
The
other type of duplication is called 'gravity-fed'. A single
moving part dispenses discs to the recorders and readers
in the DVD ROM duplication unit. Advantages include reliability
due to minimal moving parts and improved throughput speed
in reloading the discs.
In the
picture on the left, the upper left machine represents pick
and place robotics, the lower right gravity-fed. Both types
of machines can be found at

| Printing |

|
There
are also two main methods for printing on a DVD.
Thermal
Printing uses a wax transfer ribbon and a heated print head
to transfer a design to lacquer or ceramic coated media.
Advantages of this method include the durability and water
impermeability of the print, as well as having a nice professional
finished look.
Inkjet
Printing uses ink in a similar manner to paper printing.
An inkjet printer head applies ink to a disc with an ink-receptive
surface. Advantages to inkjet printing include higher-resolution,
more vibrant images, as well as lower startup costs. Both
types of printer can be found at www.microboards.com.
In addition
to these two methods, persons with higher volume requirements
often use 'silkscreen' printing to do large runs. Advantages
include a combination of high resolution and durability.
However, setup costs for this are considerably higher unless
discs are being done in quantities of thousands at a time.
