Hi-MD is a magneto-optical disc-based data storage format. It was a further development of the MiniDisc. With its release in late 2004, came the ability to use newly developed, high-capacity 1 gigabyte Hi-MD discs, in the same dimensions as MiniDisc. The last recorder and player was discontinued in 2011. Blank discs stopped production in September 2012.
