'''SHM-CD''' (short for ''Super High Material Compact Disc'') is a variant of the Compact Disc, which replaces the [[polycarbonate]] base with a proprietary material. This material was created during joint research by [[Universal Music Japan]] and [[JVC]] into manufacturing high-clarity [[Liquid-crystal display|liquid-crystal displays]].

SHM-CDs are fully compatible with all CD players since the difference in light refraction is not detected as an error. JVC claims that the greater fluidity and clarity of the material used for SHM-CDs results in a higher reading accuracy and improved sound quality.<ref>{{Cite web |last=CDJapan |title=All About SHM-CD Format |url=https://www.cdjapan.co.jp/feature/shmcd_allabout |access-date=2024-02-22 |website=CDJapan |language=en}}</ref> However, since the CD-Audio format contains inherent [[Compact Disc Digital Audio#Data encoding|error correction]], it is unclear whether a reduction in read errors would be great enough to produce an improved output.
