Often, customers enquiring for the first time are unaware
of the difference between DVD/CD Replication and DVD/CD Duplication.
The decision on whether to replicate or duplicate your project
is generally based on quantity of units required, the acceptable
turnaround time and the quality desired.
Data capabilities range from about 700MB on a CD to about
4.7GB on a DVD. This can be increased by 'overburn' techniques
and new technologies that use a second recordable layer ('dual
layer'), which can extend disc capacity to 8.5GB. HD DVD offers
up to 50GB data storage capacity. Therefore, accurate and
fast data transfer and copying methods become important.
There are two methods from which to choose when DVD
Copying or CD copying
. They are duplication and replication.
- Duplication: Commonly referred to as
“burning”, this is the process of copying the contents of
one CD or DVD to another disc using a drive with write capabilities.
This method is best for burn runs of less than 1,000 or
so. Many companies burn their data using in-house towers,
which consist of upto 21 target drives, a hard disk on which
to maintain the original source files, and the software
to control it all. Some towers even include robotic arms
and disc magazines that can hold 25, 50 or 100 discs, so
the whole burn operation can be unattended.
- Replication: This is a manufacturing
process which replicates or clones the original master.
A glass master is made, then a set of moulds or stampers
are made from the master. The stampers are then mounted
into an injection-mould machine where a replica of the mold
is created. The disc is then coated with a layer of aluminium
that is very thin and reflective. Finally, a protective
lacquer is spun onto the disc and hardened using ultraviolet
light. The replication process is typically considered for
runs larger than 1,000.
Outsource your DVD/CD project to a reputable replication
company. Earth First Infotec Limited is an established replication
company that has proven itself reliable and cost effective
in CD and DVD replication for many satisfied customers time
