M-DISC's design is intended to provide greater archival media longevity.[1] Millenniata claims that properly stored M-DISC recordings will last 1000 years.[2] While the exact M-DISC are a trade secret,[3] 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. [4][5]

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"[6][7]

M-DISC developer Millenniata, Inc. was co-founded by BYU professors Barry Lunt[12] and Matthew Linford,[13] along with CEO Henry O'Connell and CTO Doug Hansen.[14] The company was incorporated on May 13, 2010 in American Fork, Utah.[15]

History

LG Electronics, ASUS and Lite-On [9] produce drives which can record M-DISC media. Ritek produces M-DISC Blu-ray disc media, sold under the Imation, Ritek and M-DISC brands.[10][11]

M-DISC uses a single inorganic recording layer, with a higher powered laser. Thus, the M-DISC physically alters the recording layer, burning a permanent hole in the material. Recorded discs are readable in conventional drives. [8]
