DOTS is the only digital storage designed to be read with a camera employing standard image processing techniques. Data is recorded visually on patented phase-change metal alloy tape at a microscopic density that rivals the capacity of current magnetic tapes. DOTS can record any digital file format, visible text, and imagery on the same media. Using a visual method to represent the data ensures, as long as cameras and imaging devices are available, the information will always be recoverable, and backwardly compatible to the 1st generation.
