Asus has today unveiled the ASUS DRW-20B1L/B1LT internal DVD rewriter with LightScribe direct disc labeling technology. The SATA DVD rewriter provides a high speed of 20X DVD±R write, 12X DVD±R (DL) and 12X DVD-RAM reading capabilities. The specifications also include 6X DVD-Rewrite, 8X DVD+Rewrite, 16X DVD-ROM, 48X CD-Write, 32X CD-Rewrite, 12X DVD-RAM and 48X CD-ROM - further providing flexible and high-speed operations.

The ASUS DRW-20B1L/B1LT comes equipped with the Optimal Tuning Strategy (OTS) for improved disc burning and better overall write quality. With OTS, the drive will perform a test burning before actually burning the disc - intelligently calculating the best burning strategy based on operating temperatures and media and drive variations. This provides the users with optimal write speeds for the new disc. After the disc is burnt, OTS memorizes the particular type of disc, and utilizes the same burning strategy when the same type of disc is used. This not only reduces the possibility to burn unplayable discs, it also provides high quality backups and improves compatibility so that the disc can more easily be read by other drives; as well as extending the lifetime of the drive.

Another innovation of the DRW-20B1L/B1LT is the E-Green Engine technology. This feature provides an E-Green Mode which activates when the drives are idle for 2.5 minutes. Once activated, drive applications are closed when not in use to help conserve energy. According to Asus' calculations: on average, the PATA and SATA versions of the drive will provide 75% and 27% power savings respectively over competing solutions.

Besides boasting fast speeds, the LightScribe technology is also able to provide users with customized disc labeling.
