Ritek has succeeded in developing advanced dyes for making DVD+R DL (single-sided, double-layer) discs, becoming the second company to develop the dye after Japan-based Mitsubishi Chemical, according to company spokesman Eric Ai.

Ritek's DVD+R DL discs can be burned at 2.4x speed with high success rates and 4x speeds with limited success, Ai pointed out. The company is making efforts to develop more advanced 8x DVD+R DL discs as well, Ai indicated. Currently, Ritek ships more than 100,000 DVD+R DL discs a month.

In addition to the migration to next-generation blue-laser technologies, Ritek CEO Gordon Yeh believes introducing multiple layers to increase storage capacity is an important trend in the development of DVD disc technology.
