Blu-Ray Disc Players IntroductionThe first Blu-ray disc players were launched in the UK in 2006 and the range available is predicted to expand dramatically as the Blu-ray disc gradually replaces the DVD. What is a Blu-ray Disc Player?The Blu-ray disc player is a new type of audio-visual equipment specifically designed to play Blu-ray discs. The Blu-ray disc is a new optical disc format designed to ultimately replace the DVD. Developed by a group of leading consumer electronics companies, including household names such as Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson, the Blu-ray disc uses a blue-violet laser to read and write data rather than the red laser used when reading and writing CDs and DVDs. The blue-violet laser can be focused on data more accurately because it has a shorter wavelength than the red laser, and so Blu-ray discs can store up to five times the amount of data that can be stored on CDs or DVDs. A single-layered Blu-ray disc can store up to 25GB of data, and a dual-layered Blu-ray disc can store up to 50GB of data. A 50GB Blu-ray disc can hold over nine hours of high-definition video content or around 23 hours of standard definition video content, meaning that it has the capacity to store far more special features and content than a DVD, and it can also support more interactive menus and graphics. This extra storage capacity also means that the Blu-ray disc can support high-definition (HD) audio and visual formats, so youll be able to enjoy your favourite movies in HD. The Blu-ray disc is also more scratch-resistant than a DVD as its hard-coated, so your discs should last longer. Blu-ray disc players are also backwards-compatible, so youll still be able to play your old DVD collection you wont need to replace all your movies overnight! Advantages of a Blu-ray Disc Player
