Super High Material CD

SHM-CD is a digital optical disc data storage manufacturing process. It is an improved compact disc product with the greatest change being a different polycarbonate material that allows more precise physical representation of stored bits during pressing and less laser scatter during reading. These improvements aim to facilitate playback by producing fewer errors and potentially better sound quality. SHM-CDs are played on a standard CD player.

This process was developed in Japan by Universal Music Japan and JVC. The same material can also be used to manufacture SHM-SACD discs.
