Facts About CD And DVD Replication

By Frank Hayes


CD and DVD replication is the process of producing commercial CDs and DVDs in high quantities using a master version created from a source data recording. This process is used in the mastering of read-only CDs and DVDs. Disk replication companies can ensure error free, high quality disks of up to 500 to millions in just one production run.

The DVD mastering process differs from burning in that the pits and lands of the master DVD is moulded onto a blank disk. Burning involves a process of burning into the dye layer and is not as reliable. So the pressing plant produces each disk individually rather than using a sequential burning process.

The master is thoroughly checked for any errors. Dust, hairs and other small objects can render the master useless. If the master is verified as 100% ok then duplications are made. A test pressing is made initially in order to check for quality, an analyzing machine is used to check disks for consistency.

The teat pressings are analyzed by an experienced machine operator. They will be experienced enough to be able to analyze the data and fine tune the process of moulding the disks. Each CD or DVD will have any artwork printed on it in high quality using a xerox machine during the moulding process.

The master operator will go through several tests to check the quality, readability and playability of the source data. If there are any problems these will be immediately discussed with the customer. The source data is kept on the mastering machine's hard drive, . When the master is produced it is compared to the source data and checked for any errors.

These companies attract many different clients. These can be from Governmental organization, business, music companies and educational organizations. A good service will guarantee a turnaround of within 48 hours. Companies usually work 24/7 and on public holidays, so clients can contact at any day or night.
