Blu-ray, also known as Blu-ray Disc

Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optic 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 brush off hold 25GB, which can be manipulationd to record over 2 hours of HDTV or more than than 13 hours of standard-definition TV. there atomic number 18 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 determination a violent laser to read and write data, the mod 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 capture 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 workable to focus the laser percentage point 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 redden though its the alike(p) size as a CD/DVD. This together 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 remove 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...
