CD & DVD Extraction Knowledge Centre
A specialist guide to extracting and preserving audio, video and data from optical discs.
Explore Oxford Duplication Centre's guides to CD and DVD extraction, optical-disc recovery, disc imaging, audio extraction, DVD-Video structures and digital preservation.
CD audio extraction
CDs and DVDs are not one single type of digital media. Their contents can range from Red Book audio and ordinary computer files to authored video structures and mixed-mode publications.
CD data extraction
Use these guides to identify the source correctly, understand the extraction method and plan preservation outputs.
DVD video extraction
Optical media should be migrated into managed digital storage before ageing media or obsolete playback equipment makes recovery difficult.
DVD data extraction
Oxford Duplication Centre can handle audio, video and data extraction as part of a documented digitisation workflow.
Disc imaging
See the individual guides for technical explanations and preservation considerations.
Reference guidance: This article is informed by optical-media preservation guidance from the U.S. National Archives and the Library of Congress Recommended Formats Statement. Where appropriate, the article distinguishes preservation guidance from practical extraction procedures.
