What does M-DISC mean?

Millennial Disc (M-DISC) is a write once optical disc technology available in DVD and Blu-ray forms. Normal DVD’s and Blu-ray disk uses an organic dye layer to store the data. Organic dyes start to degrade and fade as soon as they are written, leading to a condition sometimes called “data rot”. M-DISC uses an inorganic metal oxide layer to store the data, which should have very long term stability compared to the organic dyes found in normal DVD and Blu-ray disks.
