What is Blu-ray?

Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation
optical disc format jointly developed by the Blu-ray Disc Association (BDA), a
group of the world's leading consumer electronics, personal computer and media
manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic,
Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was
developed to enable recording, rewriting and playback of high-definition video
(HD), as well as storing large amounts of data.

The format offers more than five times the storage capacity of traditional DVDs
and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc.
This extra capacity combined with the use of advanced video and audio codecs
will offer consumers an unprecedented HD experience.

While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-
RAM rely on a red laser to read and write data, the new format uses a blue-violet
laser instead, hence the name Blu-ray. Despite the different type of lasers used,
Blu-ray products can easily be made backwards compatible with CDs and DVDs
through the use of a BD/DVD/CD compatible optical pickup unit. Blu-ray
technology allows data to be packed more tightly and stored in less space, so it's
possible to fit more data on the disc even though it's the same size as a CD/DVD.
