Baldie used our newssubmit to tell us that Oak Technology has developed a 48 speed CD-R/RW controller that enables companies that use their chipset to make CD-RW drives that can write at 48 speed.
The controller is also able to rewrite at 24 speed. You can recognize CD-RW drives that use the Oak Technology chip by their ExacLink on board technology that is just another name for technology to prevent buffer underruns:
The OTI-9797T controller is capable of 48X CD-R as well as 24X CD-RW write speeds, and is pin-compatible with Oak's 32X OTI-9797S controller to provide an easy upgrade path and a fast time-to-market for OEMs. The OTI-9797T is suitable for use in PC-based or consumer audio CD-R/RW applications with IDE interfaces. Supporting Constant Angular Velocity (CAV), an advanced writing technique that achieves 20 percent faster write times than Zoned Constant Linear Velocity (Z-CLV)-enabled drives, the OTI-9797T will enable drives to record a full 650 Megabyte compact disc in just over two minutes. |
"The ability for consumers to capture and store music, data, and video applications on CD-RW media is growing at an exceptional pace, and not surprisingly, consumers are demanding faster recording speeds," said Clark Foy, vice president, product marketing, for Oak's Optical Storage Group. "As drive speed continues to migrate upward, Oak is aggressively advancing CD-RW technology and delivering to that demand."
Oak's OTI-9797T controller employs advanced features to achieve the fastest overall recording times while still maintaining high reliability and buffer underrun protection. By supporting CAV at the platform level, the OTI-9797T simplifies integration of this feature for drive OEMs with no previous CAV writing experience, and enables faster write access times for packet writing to CD-RW media. For best performance, the new controller also incorporates support for the Mt. Rainier standard, which allows OEMs the ability to offer drag-and-drop CD rewriting and on-the-fly formatting of the disc. Integrating Oak's patent pending ExacLink™ buffer underrun protection, the OTI-9797T is one of the most reliable CD-R/RW controllers on the market.
Well I guess I know what most people will say is, who needs the few seconds it will take less to write to a CD, I guess it also more marketing then really an improvement. But 48 speed at CAV is pretty nice
