"...Oak Technology today unveiled one of the industry's first integrated Compact Disc -- ReWritable (CD-RW)/DVD "Combo" controller, which will allow optical storage drive manufacturers to develop high-performance optical storage solutions capable of reading and writing Compact Discs and reading DVD discs from a single slim line drive. The OTI-9897 combo controller creates a fully integrated solution for a combo drive that can significantly reduce both the time to market and the bill of materials for OEM manufacturers.

Oak's OTI-9897 combo controller is capable of 16X CD-R and 16X CD-RW write speeds as well as 40X CD-ROM and 8X DVD read speeds. It supports all DVD media types by reading DVD-ROM, DVD-R, DVD-RAM, DVD-RW, and DVD+RW discs. The single-chip controller integrates an Ultra DMA IDE/Atapi controller, CD block decoder/encoder, CD-DSP, DVD-DSP, CD/DVD servo, CD wobble servo, CD write strategy, and CSS content protection authentication.

The combo controller uses advanced digital signal processing techniques to minimize the amount of required analog circuitry. This approach provides increased flexibility and greater immunity to system noise. An advanced architecture affords a high level of accuracy and improved seek access time, particularly for CD-RW media. Power management is provided to reduce power consumption and increase power efficiency. Oak's OTI-9897 combo CD-RW/DVD controller is sampling now and will be available in production quantities in second quarter 2001..." NULL
