Philips Electronics has announced a highly integrated chipset, optical pickup unit (OPU), firmware and reference design for what are claimed to be the industry's highest-speed DVD recorders.
According to Philips, optical drive manufacturers targeting the PC industry can now bring consumer products to market quickly.
The Philips DVD design also incorporates new technology to minimize recording errors caused by common disk defects such as fingerprints. The software and chipset, based on Philips Nexperia streaming media technology, will allow consumers to create 4.7-Gbyte DVDs of home videos, photo albums and PC data in less than 15 minutes, or half the time of existing drives.
Designed primarily for PC use, the Nexperia DVD+R/RW system solution can support record speeds up to 8x. This increase in recording speed is achieved by a new approach to optical recorder design: the write strategy generator (WSG) has been moved to the same board as the laser driver, eliminating the data bottleneck that limited recording speed. The new design also supports disk reading during the record process, which in turn supports an innovation to eliminate most recording errors caused by common defects on the disc surface, and ensures higher levels of compatibility with legacy DVD players.
The Philips chipset includes the PNX7850 main processor, the TZA1039 analog processor and the TZA1047 laser power controller. The entire system is designed to work with the Philips OPU66.20
