M\-DISC developer Millenniata, Inc\. was co\-founded by[Brigham Young University](https://en.wikipedia.org/wiki/Brigham_Young_University)professors Barry Lunt,[Matthew Linford](https://en.wikipedia.org/wiki/Matthew_Linford),[CEO](https://en.wikipedia.org/wiki/CEO)Henry O'Connell and[CTO](https://en.wikipedia.org/wiki/Chief_technology_officer)Doug Hansen\.[\[10\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-10)[\[11\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-11)[\[12\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-12)The company was incorporated on May 13, 2010, in[American Fork, Utah](https://en.wikipedia.org/wiki/American_Fork,_Utah)\.[\[13\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-dhintro-13) Millenniata, Inc\. officially went bankrupt in December 2016\. Under the direction of CEO Paul Brockbank, Millenniata had issued[convertible debt](https://en.wikipedia.org/wiki/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\.\[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*\] As of the 2020s, there are only 2 licensed manufacturers of M\-Discs:[Ritek](https://en.wikipedia.org/wiki/Ritek), sold under the Ritek and RiDATA brands, and[Verbatim](https://en.wikipedia.org/wiki/Verbatim_(brand))with co\-branded discs, marketed as the "Verbatim M\-DISC"\.[\[14\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-14)[\[15\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-15) 128GB[BDXL](https://en.wikipedia.org/wiki/BD-XL)never made it to market due to the 2016 bankruptcy\.\[*[clarification needed](https://en.wikipedia.org/wiki/Wikipedia:Please_clarify)*\]\[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*\] Early in 2022, Verbatim changed the formulation of their M\-DISC branded Blu\-rays\. These new discs could be written at a faster rate than the previous ones – 6× speed instead of 4×\. The new discs also had different colouration and markings compared with older version\. Later in the year customers accused Verbatim of selling an inferior product and deceptive marketing\.[\[16\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-16)Verbatim responded that the new discs were a further development of the older discs and should have the same longevity, and that the technical changes therein were responsible for the altered appearance and higher write speeds\.[\[17\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-17)The updated M\-DISC currently sold on the market uses the same metal ablative layer \(MABL\) metal oxide inorganic recording layer used in many of Verbatim's regular Blu\-ray products\.[\[18\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-:1-18) The original M\-DISC DVD\+R was tested according to ISO/IEC 10995:2011[\[19\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-19)and[ECMA\-379](https://www.ecma-international.org/wp-content/uploads/ECMA-379_3rd_edition_june_2010.pdf)with a projected rated lifespan of several hundred years in archival use\.[\[20\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-20) The glassy carbon layers, in theory if preserved correctly in an environment like a salt mine, could store the data for over 10,000 years before going outside of readable specifications\. However, the[polycarbonate plastics](https://en.wikipedia.org/wiki/Polycarbonate), which are commonly used by almost all optical media and heavily in[CBRN](https://en.wikipedia.org/wiki/CBRN_defense)and[ballistic](https://en.wikipedia.org/wiki/Ballistic_shield)protective equipment due to their optical, physical impact and chemical resistant properties, have a lifespan rating of only around 1000 years before degradation\.\[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*\] Verbatim Japan claims that M\-DISCs now use a titanium layer to prevent moisture ingression and to provide environmental stability\.[\[18\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-:1-18)M\-DISCs sold in Japan are advertised to have a projected lifespan of 100 years or more based on internal ISO/IEC 16963 testing,[\[18\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-:1-18)while other regional Verbatim websites claim that M\-DISCs have a projected lifespan of "several hundred years" based on ISO/IEC 16963 testing\.[\[21\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-21) In 2009, testing was done by the US Department of Defense \([DoD](https://en.wikipedia.org/wiki/United_States_Department_of_Defense)\) producing the China Lake Report[\[22\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-22)testing Millenniata's M\-Disk DVD to current market offerings from Delkin, MAM\-A,[Mitsubishi](https://en.wikipedia.org/wiki/Mitsubishi),[Taiyo Yuden](https://en.wikipedia.org/wiki/Taiyo_Yuden)and[Verbatim](https://en.wikipedia.org/wiki/Verbatim_(brand))with all brands using organic dyes failing to pass the series of accelerated aging tests\. From 2010 to 2012, the French National Laboratory of Metrology and Testing \([LNE](https://en.wikipedia.org/wiki/Laboratoire_national_de_m%C3%A9trologie_et_d'essais)\) used high\-temperature[accelerated aging](https://en.wikipedia.org/wiki/Accelerated_aging)testing,[\[23\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-:0-23)at90°C \(194°F\)and 85% relative humidity inside a CLIMATS Excal 5423\-U, for 250 to 1000 hours with a mix of inorganic DVD\+R discs from MPO, Verbatim,[Maxell](https://en.wikipedia.org/wiki/Maxell), Syylex and DataTresor\. The summary of the tests states that Syylex Glass Master Disc was rated for 1000\+ hours, DataTresor Disc 250 hours\+ and M\-Disk under 250 hours\. The Syylex disc was a custom\-ordered product that could not be burned in a consumer player when they were still purchaseable from Syylex before their bankruptcy, so it was not truly in the same category as the others\. In 2016, a consumer Mol Smith[\[24\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-24)\[*[unreliable source?](https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources)*\]did real world[stress testing](https://en.wikipedia.org/wiki/Stress_testing)on the 25 GB BD\-R M\-Disc alongside TDK's standard BD\-R 25 GB disc using a copied movie, which demonstrated the reliability of M\-Disc's molding compared to standard discs; after 60 days of outdoor direct exposure the M\-Disk was played without error, while the TDK disc was physically destroyed\. In 2022, the[NIST](https://en.wikipedia.org/wiki/National_Institute_of_Standards_and_Technology)Interagency Report NIST IR 8387[\[25\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-25)listed the M\-Disc as an acceptable archival format rated for 100\+ years, citing the aforementioned 2009 and 2012 tests by the US Department of Defense and French National Laboratory of Metrology and Testing as sources\. While recorded discs are readable in conventional DVD and BD drives, M\-disc DVDs can only be burned by drives with firmware that supports the slightly higher power mode that M\-Disk requires for burning its inorganic layers, as such writing speed is typically 2× speed\. Blu\-ray M\-discs can be both written and read in most standard Blu\-ray drives and are certified by the Blu\-ray Disc Association to meet all current standard specifications as of 2019\.[\[26\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-26) Typically, the M\-Discs cost 1\.5–3× the price of standard Blu\-Ray discs with DVD M\-Discs now having sparse availability\. With the first\-generation DVD M\-DISCs, it was difficult to determine which was the writable side of the disc due to being near fully translucent, until coloring and later labels similar to that on standard DVD discs was added to discs to help distinguish the sides preventing user error\.

The regional government of the U\.S\. state of Utah has used M\-Disc since 2011\.[\[27\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-27) Some consumers and avid[datahoarders](https://en.wikipedia.org/wiki/Digital_hoarding)have adopted the format for cold digital data storage\.[\[28\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-28) ## Alternative technologies \[[edit](https://en.wikipedia.org/w/index.php?title=M-DISC&action=edit&section=7)\] Syylex Glass Master Disc:[\[29\]](https://en.wikipedia.org/wiki/M-DISC#cite_note-Blu-Ray_25GB_and_Blu-Ray_50GB_-_Fabricated_on_demand_at_the_cost_of_%E2%82%AC1000-29)these discs use etched glass and are only typically degradable by physical or chemical damage, but not by normal ageing inside an archival environment\.
