LDC's Publications Group maintains equipment to replicate data on a variety of media: CD, DVD, BluRay and hard drive.

The media disk replicators accommodate up to 200 discs without user intervention and print full color labels with high resolution graphics on the disc face.

The hard drive replicators can produce up to 15 copies at once. Hard drive releases are reserved for very large publications and range in size from 250GB to 2TB. The hard drive replicators perform diagnostics, erase sensitive data from drives in bulk and repair defective hard drives, allowing the Publications Group to maintain pools of reusable hard drives dedicated to specific projects.

These duplication systems employ hardware and software verification to ensure the reliability and quality of all releases.
