Blu-ray, also known as Blu-ray Disc

Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation visual disc format jointly developed by the Blu-ray Disc Association (BDA), a group of leading consumer electronics and PC companies (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. A single-layer Blu-ray Disc dribble hold 25GB, which can be manipulationd to record over 2 hours of HDTV or more than than 13 hours of standard-definition TV. there be also dual-layer versions of the discs that can hold 50GB. While current optical disc technologies such as videodisc, DVD±R, DVD±RW, and DVD-RAM uptake a violent laser to read and write data, the parvenu format uses a blue-violet laser instead, hence the name Blu-ray. in spite of the different type of lasers used, Blu-ray products can easily be do backwards compatible through the use of a BD/DVD/CD compatible optical pickup and kick playback of CDs and DVDs. The advance of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it come-at-able to focus the laser berth with make up greater precision.

This allows data to be jam-packed more tightly and stored in less space, so its possible to fit more data on the disc eventide though its the alike(p) size as a CD/DVD. This in concert with the counterchange of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB. With the rapid growth of HDTV, the consumer char! ter for recording HD programming is quickly rising. Blu-ray was designed with this application in judgement and supports direct recording of the MPEG-2 TS (Transport Stream) used by digital broadcasts, which makes it highly compatible...
