Blu-Ray Disc.

Blu-Ray (not Blue-ray), also known as Blu-ray Disc (BD), is the name of the next generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world's leading electronics, computer Private and media producers (such as Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). Formats that have been developed, which allows you to record, rewrite and playback high definition (HD), as well as to maintain large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can store up to 25GB single-layer disc and 50GB on a dual-layer disc. This extra capacity by using advanced video and audio codecs is to offer the consumer HD experience that has never happened before.


Although current optical disc technologies such as DVD, DVD ± R, DVD ± RW and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, the name Blu-ray. Although various types of lasers used in products Blu-ray can easily be made compatible with CDs and DVDs using the BD / DVD / CD compatible optical pickup unit. That supports the use of blue-violet laser (405nm) is that it has a shorter wavelength than the red laser (650nm), which allows the laser to focus more specifically on the ground. This allows the data is packed more tightly and stored in less space, so it is possible to fit more data on the disk, even though it is the same as CD / DVD. This, together with the change of numerical aperture to 0.85 is what enables Blu-ray to keep 25GB/50GB. Recent developments have led the Pioneer's 500 GB storage capacity on a single plate, using 20 layers.
