New 16x recording dye for DVD Recordable discs
Mitsubishi Kagaku Media Co., Ltd.
Mitsubishi Kagaku Media Co., Ltd. (MKM) today announced the successful development of 1-16x dye for DVD recordable discs.

With the drastic market change " from tape to disc " which is influenced by the strong market growth of DVD data drives and DVD video recorders, MKM has developed a new AZO dye which supports 1-16x speed writing to satisfy the continuous consumer demands for higher recording speeds.
Discs with this new dye can be used for recording at speeds between 1x and 16x.

As an optical disc manufacturer, MKM was able to fully utilize it's experience and technology for developing organic dye material for recordable optical discs.
"Our AZO dye enables precision element design, which results in excellent thermal and optical properties," said Shigeru Tamura, Chief Information Officer at MKM. "We maximized the structure to be compatible with high-speed recording, which gave the discs a wider power margin and greater sensitivity."

By designing the dye for high sensitivity to support high-speed recording, MKM controlled the heat interference between recording marks and reduced the degradation of recording marks. This minimized jitter and enabled superior recording characteristics across the entire range of available recording speeds, from 1x through 16x.
16x DVD drives are expected in the market around Q3 this year. Thus, MKM continues to meet the needs of the consumer by developing and manufacturing superior optical media products.
