5. Introduction to Duplication Modes

In order to achieve 8x or higher duplication performance, the factors that need
to be considered are:
Master Disc Reading Speed
■
Recorder Writing Speed
■
Media Writing Speed
■
If any of these factors fail to meet the 8x or higher certification, under any cir-
cumstances, you will encounter bottleneck symptoms that will delay your du-
plication time and reduce your duplication quality.
The recordable media must be certified for 8x or higher in order to have 8x or
higher recorder writing speed.
When making duplications directly from a master disc to a blank disc, you of-
ten cannot maintain true 8x speed throughout the duplication process. Due to
physical recordable DVD limitations, most DVD master discs cannot be read
at 8x or higher speeds continuously. Often the reader will fall behind the burn-
ers, and the whole process will have to slow down.
In order to avoid this issue, load the DVD master disc into a hard drive parti-
tion and then make all duplications from the hard drive. Once loaded, you can
make copies from the hard drive partition as you would from the master disc.
To simplify this process, use the "Load and Copy" option under the category
"Duplication Mode". This feature reduces the "Duplication from Hard Drive"
process to a single step. See "Copy" on page 21 for more information.
There are three options under "Duplication Modes":
On the Fly
■
The On the Fly mode instructs the duplicator to copy directly from the
master disc. The duplicator performs simultaneous read and write op-
erations without any delays.
Advantages:
Ideal for small quantity quick duplication
■
Disadvantages:
Requires a master disc for each and every run. (Could be harmful to
■
the master disc).
Maximum DVD duplication speed is typically limited to 4x or 6x.
■
Requires the master disc to be in excellent condition for error-free
■
duplication.
Load and Copy
■
The Load and Copy mode instructs the duplicator to load your master
disc into the hard drive Reserve partition and make the requested quan-
