Dell is now launching the Blu-ray drive as an optional extra on its XPSTM M1710 notebook, aimed at high-performance gaming and technology applications. Dell have this option available to customers worldwide, though it hasn't yet been extended to any other notebooks in Dell's range. Blue ray Disc has higher storage capacity, a main feature set that can be used for data storage and high-definition content delivery, and allows for backward compatibility with CDs and DVDs.

What is Blue-rayDisc?

The name Blu-ray is derived from the blue-violet laser used to read and write this type of disc. Because of this shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the common DVD format, which uses a red, 650 nm laser. In comparison to HD DVD, which also uses a blue laser, Blu-ray Disc has more information capacity per layer (currently 25 GB, but test media is up to 33 GB). However, Blu-Ray discs are expected to be more expensive than HD DVD discs, at least initially. Sony has released 50 GB recordable BDs and will soon be releasing 50 GB rewritable discs.

The Blu-ray Disc is a similar format to PDD, another optical disc format developed by Sony (which has been available since 2004) but offering higher data transfer speeds. PDD was not intended for home video use and was aimed at business data archiving and backup, although currently it is gaining popularity as an HD video format medium and PlayStation 3 medium. The UDO format is aimed at similar purposes. Blu-ray is currently embroiled in a bitter format war against the HD DVD disc.
