Crystal Disc

Crystal disc, manufactured by the largest CD factory in Japan - Memory Tech Corporation, is a revolutionary Compact Disc using glass substrate instead of polycarbonate.

This newly developed technology allows sound reproduction at a level previously unknown and is as close to the master sound source as cutting-edge technology allows. For this purpose, Crystal disc is fabricated by our Laser Disc technology cultivated over many years using the best-selected materials.

Memory-Tech calls the discs “Crystal Disc” and so far, seven titles are available in Japan with more on the way. Deutsche Grammophon has released its 1963 recording of von Karajan conducting Beethoven’s Ninth Symphony and has plans to release two other titles. EMI’s entry is a recording of the Japanese violinist Mariko Senjyu. JVC will soon offer three titles by Japanese classical artists. All the titles are mastered with JVC’s K2HD process.

■　The use of glass substrate instead of conventional polycarbonate substrate. As the reflective layer, gold is adopted in exchange for conventional aluminium.

■　For pit transcription, Photo Polymerization process(2P process) using a metal stamper is adopted. This process makes pit transcription highly precise compared with the conventional injection moulding process. The technology of the 2P process was cultivated by our production of test discs for calibrating industrial optical pickup heads.

■　Surface flatness of the glass substrate is much superior to the conventional CD. Glass substrate is hardly influenced by the variation of temperature and humidity. Furthermore, the absence of birefringence coming from the optical uniformity of the glass substrate realized a signal with extremely low noise and low jitter.
