MDISC - Computer Definition
(MillennialDISC) A recordable (write once) DVD and Blu-ray medium from MDISC, American Fork, Utah (www.mdisc.com). Introduced in 2009, MDISCs are used for archival storage that lasts for centuries. Rather than employing a dye layer, the data are etched into the MDISC's inorganic recording layer. All Blu-ray drives and newer DVD drives are MDISC-compliant for recording, but all regular BD/DVD players can read them. Via the www.mdisc.com and www.yours.co websites, users can have their cloud photos recorded on MDISC media to ensure that precious photos can be passed down to future generations. See WORM.
