Developed by the BDA, it is a next generation optical disc format which uses blue lasers with shorter wavelengths and can therefore store much more data. It is competing with HD-DVD as the standard for high-definition DVD.
A new optical disc format developed by nine of the original DVD Consortium ( Hitachi, LG Electronics, MEI, Pioneer, Philips, Samsung, Sharp, Sony and Thomson Multimedia). The new format retains DVD's physical dimensions but achieves a capacity of up to 27GB per side/layer by employing a 405 nm blue-violet laser.

Blu-ray Disc (BD) is a next-generation optical disc format meant for storage of high-definition video and high-density data (25 GB). Blu-ray gets its name from the shorter wavelength (405 nm) of a "blue" laser that allows it to store substantially more data than a DVD.
Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optical disc format. 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.
A rival to HD DVD, offering more storage capacity but still delivering high-definition movies. Already launched (as recorders) in Japan, but still some way off for the rest of the world
A high-definition DVD format supported by a group of manufacturers led by Sony.
An HD-DVD format that uses a 405nm-wavelength blue-violet laser technology, to be compared with the 650nm-wavelength red laser technology in use in traditional DVD format. The rewritable Blu-ray disc can store up to 27GB of data on a single-sided single layer disc (compared to the traditional DVD's 4.7GB capacity), which is approximately 12 hours of standard video and/or more than 2 hours of High-Definition video. It has a data transfer rate of 36Mbps. Blu-Ray is developed by a consortium gathering Sony, Samsung, Sharp, Thomson, Hitachi, Matsushita, Pioneer + Philips, Mistubishi and LG Electronics.
