The Difference: Duplication vs. Replication

duplicationHawksM09 March 2010

Today CDs can store up to about 700 MB of data while DVDs max out at around 4.7 GB, but media storage capacities are constantly trending upward, particularly with the rise in popularity overburn and dual-layer techniques.

Duplication and replication. The words may sound remarkable similar, but the differences between the two are important to point out. To make the most appropriate choice you want to make sure you know the difference when choosing the appropriate software and technology combo or professional organization for your next project.

Duplication

Duplication is often also referred to as CD burning. Whereas a single copy involves transferring from data one CD or DVD to another, the term duplication is used when referring to a media copy job that involves more than just one copy being made. Duplication jobs of about 1,000 discs or less can often completed at home or in-house with the use of a dedicated computer (or computers) with multiple burners or with a professional CD DVD duplicator.

The technology used in duplication is called laser etching, which transfers the data from one disc to another – a portable, convenient, and economical form of data transfer.

Replication

Instead of making a copy of data, replication essentially makes a clone of the original data. In replication, a glass master is created from the original version of the CD or DVD and then a mold (or set of molds), sometimes referred to as stampers, is created from that glass master. The process of replication allows for every disc to be a first-generation replica. The stampers act as a blueprint; they are used with high-injection molding to make a plastic disc-like molded clone. The clone is covered with a thin layer of aluminum and sealed with a layer of laquer, which is hardened by ultraviolet light.

Because of its technical nature, replication is typically used for large-scale jobs of 1,000 or more (the larger the quantity, the lower the cost) and is usually completed by a disc replication company. Replication services offered by these companies often include printing and packaging services as well, and the quality of the replicated discs is often higher than duplicated discs. The difference in price can be substantial: a job of 300 discs may cost about $2 disc, whereas a job of 1,000 can drop to about $0.50 per disc. The bulk of the additional costs for replication come from the set up fees.
