Taiwan-based optical disc maker Ritek on August 10 announced it is undertaking pilot production of 50GB single-sided double-layer (DL) BD-R (Blu-ray Disc recordable) discs and will kick off volume production in the fourth quarter of 2010 with an initial monthly output of 150,000-200,000 discs.
In addition, Ritek and a Japan-based fellow maker have been cooperating to develop 100GB single-sided triple-layer BD-R, BDXL, discs, with the development expected to be finished in the first half of 2011 and volume production possibly to begin in the second half, Ritek said.
Ritek has introduced PTM (phase transition mastering) technology to the development of BDXL in order to shorten time to market and control production cost, the company indicated. The technology was developed by the Electronics & Optoelectronics Research Lab under Taiwan government-sponsored Industrial Technology Research Institute (ITRI), Ritek noted.
Production of 50GB DL BD-R discs will have a gross margin of 50%, much higher than the 30-40% for 25GB single-layer BD-R discs, Ritek said.
