Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optic book put 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 stage was developed to alter enter, rewriting and playback of high-definition video (HD), as well as storing cock-a-hoop amounts of data. A single-layer Blu-ray Disc tin express 25GB, which nooky be manipulationd to record over 2 hours of HDTV or more than(prenominal) than than 13 hours of standard-definition TV. there ar also dual-layer versions of the discs that can hold 50GB. While current optical disc technologies such as videodisc, videodisk±R, videodisk±RW, and DVD-RAM use a violent laser to engage and write data, the new format uses a blue-violet laser instead, and then the name Blu-ray. in transgress of the different type of lasers utilise, Blu-ray products can easily be do backwards compatible through the use of a BD/DVD/CD compatible optical pickup and allow playback of CDs and DVDs.

This allows data to be packed more tightly and stored in slight space, so its possible to check out more data on the disc even though its the alike(p) size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB. With the speedy growth of HDTV, the consumer demand for recording HD programming is quickly rising.
