M-Disc are supposed to last 100-1000 years. They literally engrave data into an inorganic layer with high melting point instead of writing to a dye.

  >They literally engrave data into a polycarbonate with high melting point instead of writing to a dye. Are you sure you're not talking about pressed (ie. mass produced) discs? I find it unlikely that a blu-ray/dvd burner equipped with only a laser can "engrave data into a polycarbonate with high melting point".

    > Verbatim M DISC™ optical media is the new standard for digital archival storage. Unlike traditional optical media, which utilize dyes that can break down over time, data stored on an M DISC is engraved on a patented inorganic write layer – it will not fade or deteriorate. This unique engraving process renders these archival grade discs practically impervious to environmental exposure, including light, temperature and humidity. https://www.verbatim.com/subcat/optical-media/m-disc/ https://www.verbatim.com/subcat/optical-media/m-disc/

      One wonders why M-DISC is not included in the original article at all.
