Recordex TechDisc Pro CD
®
TM
Your TechDisc Pro™ is designed to make thousands of copies at high speed. For the best results we recommend that you
use the highest grade media available. Higher grade media may cost a little more but the you will have fewer failures
when copying at high-speed. Recordex recommends that you contact the dealer or retailer where you bought your duplica-
tor and ask them to recommend a high-quality disc for duplication.
There are a few steps you can take to make sure that your source discs, also called master discs, are optimized for high-
speed duplication.
Disc Capacity
Make sure the disc is not too full. Due to differences in discs and disc drives it is important to not fill the disc too full or you
may experience something called a target over flow error. This happens when the system determines that the source disc
contains more data than will fit on the target discs. A good rule of thumb is to keep discs below these size guidelines:
•
DVDs should be 4.38GB or smaller
•
CDs should be 685MB or smaller
Disc Surface
Both the master and target discs need to be clean and free of any blemishes. Even fingerprints can cause issues when copy-
ing at high speeds. For best results use new media that has not been previously handled and always pick up discs by their
edges and avoid touching the data surface of the disc.
Disc Quality
As mentioned above disc quality is important when copying at high speeds. Using the cheapest media may result in a high-
er rate of copy failures.
A failed disc is often called a
coaster
because it is good for little else than keeping your coffee table free from
drink rings!
