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. The Verbatim M-Disc 4X BDXL is inkjet and hub printable, allowing you to create custom disc surfaces and artwork for your discs. Compatible with the latest inkjet disc printers, the printable surface offers full-surface, edge-to-edge printing and rapid-dry ink absorption for clear text and photo-quality images.
