Building on the ArchiveLaser® project, which was presented during the 2005 IS&T Archiving Conference, the further developments of the technology that have taken place in the followup NOAH project will be displayed in this paper. It will present a complete system that is able to store digital data as a bit stream on long-term stable optical film (microfilm) and retrieve it afterwards with simple optical scanners. The complete workflow has been demonstrated at the CeBIT fair in Hannover, Germany, in March 2006. One of the core achievements of our research is the density of more than 1 Terabyte per reel of film. This data carrier enjoys all the characteristics and advantages of an optical, analog data carrier: long-term durability of up to 500 years, no manipulation or virus attacks and independence from rapidly changing soft- and hardware generations. This workflow addresses storage providers, whose data necessarily has to be stored for more than 4 years and where the total cost of ownership, including a solid guarantee for future accessibility to this data, is crucial.

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.
