One of the most efficient ways of storing large amount of information would be storing at compact disc. CDs can store information up to 700 megabytes and we can easily access this information anywhere. A CD writer is required to write the complete information and people can access information from the disc itself. The entire process of saving and reading information is found to be quite simple. Laser lens built in the CD writer makes the entire process easier. Great demand for CD replication can be seen in various places in the world, especially in Australia, Japan, Germany and America. Different companies providing these services can be found in demand for its products and services. This kind of replication process is found to be quite simpler and it is done by expensive and automated equipment.
But, there is a difference between CD replication and CD duplication. In case of replication, it is found to be professional process creating a CD by molding the disk to be an exact copy of the original master. No data can be added or changed in this process. In case of CD duplication, burning of the data to a disk can be done in home computing. While duplicating CDs for personal use, it is found to be quite inexpensive and easy. Thus, it is found to be better choice for low-run needs. Different CD burners and popular software are found to be effective for duplicating audio tracks or data files to CD-R (recordable) or CD-RW (read/write) disks.
In case of replication process, it is possible to make multiple copies of CDs with the same information and similar prints on the CDs. These are made in large volumes and they can be extended to CDs, DVDs, business cards, mini discs and other storage media.
Though duplication and replication are found to be two separate processes; but, they have been confused by many people.
