Blu-ray Disc
It is the next generation optical packaged media disc format. It was named as Blu-ray for the reasons that the laser beam which reads the data from the new discs is blue violet instead of red. This so called blue laser disc technology has a shorter wave length than a red laser, that makes it possible to read data with greater precision. The format was developed to enable recording, rewriting and playback of high-definition video, as well as storing large amounts of data. Great privilege of watching

HD DVD

The HD (High-Definition) DVD standard is designed to be the successor to the standard DVD format, and is derived from the same underlying technologies. It is a next-generation optical disc format, featuring a significant increase in storage capacity facilitating support for high definition (HD) video and audio. The HD DVD name is derived from its origination as a high-definition extension of the DVD optical disc format.

High-Def Market share

From the average consumer's stand-point, there is little difference between the two technologies. Both formats offer support for HD audio and video and they both have the potential to emerge as the sole successor to DVD. Some of the major differences are BD's higher production costs and superior storage capacity of 23.3GB per layer vs HD's 15GB.

Other Interesting facts:

* The Nichi Corporation, who holds the design patents to the Blu-ray's laser system, sits as an associate member of the HD DVD Promotion Group.

* Even though Apple sits on the Blu-ray Board of Directors, its DVD Studio Pro software supports authoring HD DVD media.

* Blu-ray, unlike HD DVD, requires a hard coating on its discs because it's 0.5m closer to the surface. The polymer coating it uses, called Durabis, was developed by TDK and is supposedly extremely resilient and fingerprint resistant.

* The Java platform is mandatory on Blu-ray as it's the standard for menus/multimedia (i.e. all Blu-ray systems must support JVM)

* DVD version of the Xbox 360 is rumored for the future.

* The first consumer Blu-ray device in the US market is expected to be the PlayStation 3.
