We report on the test results of a recently fabricated data reader for our Write Once, Read Forever (WORF) high-density, very long-term archival data storage system. At the 2014 and 2015 IS&T Archiving conferences we described our technology and our progress establishing that multi-state data can be stored on monochromatic, dye-free, silver halide (AgX) media using our patented processes. WORF "freezes the wavelength" configuration of light within the media, which is restructured as a data constellation. Hitherto unreported chemical and optical phenomena are documented. WORF presents novel opportunities for security, encryption, data compression, and simple information recovery for the far future. It is known that AgX will last many centuries in ambient room temperature without continuous energy inputs or continual replication and authentication. This is an "existence proof" for the long-term archivability of data storage based on AgX chemistry.

More about this publication?
  • The IS&T (digital) Archiving Conference offers a unique opportunity for imaging scientists and those working in the cultural heritage community (curators, archivists, librarians, photographers etc) from around the world to come together to discuss the most pressing issues related to the digital preservation and stewardship of hardcopy, and other cultural heritage documents and objects. Authors come from museums, archives, libraries, government institutions, industry and academia. Cutting edge topics related to multispectral and 3D imaging, as well as best practices for workflow, sharing, standards, and asset/collection management and dissemination are explored in papers presented at this annual, international event.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in pertuity. Copyright restrictions on papers vary; see individual paper for details.
