Philips 65100 manual Bur Management From Philips, Page, Several primary sources of BUR are

Fig. 3, Typical CD writing process: Buffer under run occurs and results in writing failure, disc is ruined.

CD writer

Writer buffer level drops to 0%

·No more data available to write to the CD

·Writing stops => BUR

BUR occurs when this stream is interrupted

Several primary sources of BUR are:

·Insufficient PC processing power (low speed CPU, DRAM size, no DMA support)

·System configuration not optimal (DMA switched off )

·Too much user interaction during CD writing (launching or running additional applications)

·Insufficient performance of the source drive (CD ROM or HDD in user system or network)

·Insufficient performance from the mastering software, espec. at higher recording speeds

·Insufficient performance of the writer (not enough internal memory or buffer…)

·Scratched or dirty media (source drive needs multiple retries to successfully read)

BUR MANAGEMENT FROM PHILIPS!

Seamless Link, the Philips solution, is a BUR management solution that is “on board” the drive and prevents a lost disc when a buffer under run occurs during TAO or DAO writing. Detecting the clues of a imminent BUR ahead of time, Seamless Link pauses the writing in a controlled way, and restarts the writing when the danger of the BUR is gone. The result is effective with most older systems, when proper system set-up is done, and Seamless Link works transparently with most writing application software.

The primary benefits to users of both new and older PC systems are:

·The Philips "intelligent drive" pro actively manages the consequences of a BUR during CD writing

·The solution allows users greater ability to launch and run other applications..., or surf the web, while burning a CD.

Although Seamless Link is an excellent tool for managing the impact of BUR when it occurs, Seamless Link does not improve writing quality.

For improvements in writng quality, refer to the Philips' Thermo-Balanced Writing (TBW) white paper.
