Super High Material (SHM) CD is a type of Compact Disc that uses an improved transparency polycarbinate resin as its transparent substrate, and this is claimed to provide a clearer medium for the reading of the data and so reduce read errors and improve the sound quality.
The polycarbinate resin was developed by JVC and Universal Music Japan during research into LCD manufacturing, and SHM-CDs began to be released in 2007.
SHM-CDs are fully compliant with the Red Book standards and play in any Compact Disc player.
Almost all of the releases have come from Japan, and have mostly been re-releases.
