CMC and Ritek get class-A verification for 1x HD-DVD-R SL discs

CMC Magnetics has received the class-A verification for its 1x HD-DVD-R SL (high-definition DVD-R single-sided single-layer) discs with 15GB storage capacity from the DVD Forum last week, while Ritek indicated it obtained the same level of verification in late May of this year, according to DigiTimes.

Class-A verification indicates that a product meets the minimum specifications laid out by the DVD Forum.

CMC and Ritek have started shipments of 1x HD-DVD-R SL discs in small volumes this month, according to the two companies. However, second-tier makers of optical discs in Taiwan, including Prodisc Technology, Lead Data and Gigastorage, are still in the R&D phase of next-generation blue-laser disc technology and may begin volume production around the end of this year or early next year, industry sources pointed out.
