According to DigiTimes, Ritek announced it has received the certification for both HD DVD-R and HD DVD-RW formats, becoming the only Taiwan-based producer of optical discs to receive certification. The technological barrier for HD DVD-R is quite high and that for HD DVD-RW is higher, Ritek indicated.

Ritek's manufacturing capability for DVD+R/-R DL (single-sided double-layer) discs was helpful in obtaining the certification, the company pointed out.

Volume production for the two formats will kick off in the second half of this year at the earliest, Ritek noted.

CMC Magnetics received certification for Blu-ray Disc (BD)-R production last month and may begin volume production next quarter, according to industry sources.
