With industry-leading expected disc lifetimes and 120 minutes of DVD quality storage capacity, M DISC DVDR are an ideal archival solution for home movies and video clips, as well as backing up music and video libraries. 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. Unlike hard drives or tape-based media, this optical disc is not vulnerable to damage from magnetic fields. It is write-once, meaning that once data is recorded, it cannot be accidentally erased. To burn M DISC media, you will need an M DISC ready drive. Drives that are M DISC ready will often have the M DISC logo on the drive. Fully backward-compatible optical drives should be able to play M DISC media. More from the Manufacturer
