M-DISC's design is intended to provide greater archival media longevity. Millenniata claims that properly stored M-DISC recordings will last 1000 years. While the exact M-DISC are a trade secret, the patents protecting the M-DISC technology asserts that the data layer is a "glassy carbon" and that the material is substantially inert to oxidation and has a melting point between 200°-1000 °C. 
A stress test was performed by the Department of Defense of the media, proving at the very least that M-Disc DVDs and Blu-rays are more durable than conventional DVDs and Blu-rays. "The discs were subject to the following test conditions in the environmental chamber: 85°C, 85% relative humidity (conditions specified in ECMA-379) and full spectrum light"
Conventional DVD-R and BD-R LTH (Low To High) use recording layers of organic dye and separate reflective layers. Standard (HTL) BD-R and BD-R/DL typically use inorganic data layers, but continue using a reflective layer. M-DISC uses a single inorganic recording layer, which is substantially inert to oxygen, but requires a higher powered laser. M-DISC does not require the reflective layer. Thus, both the M-DISC, and inorganic BD-R, physically alter the recording layer, burning a permanent hole in the material. Besides physical damage, failure of the reflective layer, followed closely by degradation of the data layer, are the primary failure modes of all optically recordable disks.
Recorded discs are readable in conventional drives.
M-DISC developer Millenniata, Inc. was co-founded by BYU professors Barry Lunt and Matthew Linford, along with CEO Henry O'Connell and CTO Doug Hansen. The company was incorporated on May 13, 2010 in American Fork, Utah.
