Test Data Reader For Write Once, Read Forever (Worf) Interference Spectra Archival Media

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.
