While HD DVD writers are few and far between, this hasn't stopped Ritek from developing media for them. The company received certification for their 1x HD DVD-R and 1x HD DVD-RW media back in May and, according to a report by DigiTimes, recently obtained certification for their new 2x HD DVD-R discs.
Ritek, the second largest Taiwan-based maker of optical discs, has secured certification for blank 2x HD DVD-R (recordable, write once) discs, according to industry sources in Taiwan. The company had already achieved certification for its 1x HD DVD-R and 1x HD DVD-RW (rewritable) discs in May 2007.

In addition to the HD DVD format, Ritek has obtained certification for blank BD (Blu-ray Disc)-R discs, while CMC Magnetics, the largest Taiwan-based maker, received the same certification earlier in late April of this year, the sources indicated. Japan-based Mitsubishi Kagaku Media (MKM), Matsushita Electric Industrial (with Panasonic as brand name) and TDK were the first three recipients of such BD-R disc certification, the sources noted.
