M-DISC (Millennial Disc) is a write-once optical disc technology introduced in 2009 by Millenniata, Inc.[1] and available as DVD and Blu-ray discs.[2]

M-DISC's design is intended to provide greater archival media longevity.[3][4] Millenniata claims that properly stored M-DISC DVD recordings will last 1000 years.[5] The M-DISC DVD looks like a standard disc, except it is slightly thicker and almost transparent.

M-DISC developer Millenniata, Inc. was co-founded by Brigham Young University professors Barry Lunt[7] and Matthew Linford,[8] along with CEO Henry O'Connell and CTO Doug Hansen.[9] The company was incorporated on May 13, 2010, in American Fork, Utah.[1]

Millenniata, Inc. officially went bankrupt in December 2016. Under the direction of CEO Paul Brockbank, Millenniata had issued convertible debt. When the obligation for conversion was not satisfied, the company defaulted on the debt payment and the debt holders took possession of all of the company's assets. The debt holders subsequently started a new company, Yours.co, to sell M-DISCs and related services.

While the exact properties of M-DISC are a trade secret,[10] the patents protecting the M-DISC technology assert that the data layer is a "glassy carbon" and that the material is substantially inert to oxidation and has a melting point between 200 and 1000 °C.[11][12]
