About SHM-CD

SHM-CD (Super High Material CD) is a superior quality CD fully compatible with all CD players. SHM-CD utilizes a polycarbonate material originally developed for LCD screens, and the enhanced transparency of the SHM-CD results in more clarity, depth and definition of sound, bringing the listener ever closer to the music of the original master.

＊Results may vary depending on playback environment.

Features of the SHM-CD: Production

The injection molding system developed by JVC KENWOOD enhances the increased fluidity and greater transfer qualities of the polycarbonate, creating a new and improved disc in a compatible CD format.

The machine utilizes a precision master metal stamper also developed by JVC KENWOOD.
SHM-CD has it’s own production line, exclusively created for manufacturing SHM-CDs.

At JVC KENWOOD, we take pride in this meticulous production process, and prioritize quality over quantity.

Features of the SHM-CD: Quality

Every SHM-CD is made from a highly transparent polycarbonate originally designed for LCD screens.
Increased fluidity and greater transfer qualities of the polycarbonate allow for finer precision in pit formation.
Cleaner audio signals reduce jitter and the effects of birefringence.

Birefringence is the refraction of light in two slightly different directions to form two rays, scattering the radar and leading to poor reading. The superior transparency of this polycarbonate substrate (1.2mm thick) reduces the effects of birefringence resulting in a more accurate reading by the laser (780nm).

Features of the SHM-CD: Hardware

Conforms to the Red Book specification and definition of a Compact Disc Digital Audio.
Compatible with all CD players.
A CD with exceptional qualities across the board.
Superior manufacturing process extracts the highest possible sound quality.
