This differs from common digital storage techniques such as drives that need to be re-written often to prevent loss or corruption of data.

WORF uses a novel high-density patented[1][2][3][4][5] data storage mechanism based on silver halide, which after substantial testing has been determined to last for more than a century under conventional ambient environmental conditions.

[6][7] WORF digital data is stored as microscopic, metallic, interference-created standing waves (representing narrowband ‟colors” ) embedded in a modern, super-resolution, dye-free, photosensitive emulsion.

The HELIOS mission returned to Earth and was deemed a success with the stored data showing no significant decay after six months of space conditions and solar radiation.

WORF technology for the HELIOS experiment uses a proven archival media, redesigned, re-purposed and patented by CTech to store digital data for long periods, measured in decades and possibly centuries.
