CDs and DVDs are a great invention of our times used by many individuals and companies for various purposes. As the cost of manufacturing original CDs and DVDs is quite high, CD/DVD replication and duplication services are being used by many people.Often people consider CD or DVD replication and duplication services to be the same, but in fact they are quite different in many ways. Although CD/DVD replication and CD/DVD duplication is used for creating new CDs or DVDs, the manufacturing process is quite different.In CD/DVD replication, new CDs/DVDs are manufactured by embedding in the data that has been provided by the organisation or person who has ordered the CD/DVD replication. A replicated CD/DVD is unique and has its own characteristics which are very close in quality to an originally created CD/DVD.In the case of CD/DVD duplication, already manufactured blank CDs/DVDs are used for copying the content of the master CD/DVD provided by the person or organisation that has placed the order. Each duplicated CD/DVD is a copy and has all the characteristics of the master CD/DVD.Duplicated CDs/DVDs are slightly inferior in quality when compared to replicated CDs or DVDs. CD/DVD replication orders must be more than 500 pieces in number while CD/DVD duplication services can be obtained by ordering fewer numbers of CDs/DVDs. The commercial sector is the major user of CD/DVD replication services while personal and non profit organisations usually go for CD/DVD duplication services.
