Ritek has announced a new combination of optical drive and discs that should have a lifetime of up 1000 years. The Taiwanese optical disc manufacturer has developed this in cooperation with Millenniata, an American company specialized in permanent archival technology.
The M-Disc technology dubbed as write once, read forever, uses an inorganic dye that according to both companies lasts centuries. Traditional optical discs contain an organic dye that is etched with a laser. The M-Disc technology also uses a laser to write data, but a different one than found in normal optical drives.
Currently only drives from Hitachi LG Digital Storage (HLDS) are able to write to M-Discs, all other commercial available optical drives are able to read them. Now one wonders what happens when people find data back in 1,000 years, are they still able to read it back anyway?
