Blu ray players
If you live in the US or Canada you can already find to buy blu ray players from Samsung, Panasonic, Sony, Philips and Pioneer available in stores, as well as a growing selection of Blu-ray movies. We also expect to see Blu-ray players from LG and Sharp, as well as a second-generation Blu-ray player from Samsung introduced in the near future.
The first Blu-ray Disc player was perceived as expensive and buggy, and there were few titles available. Now the blu ray players work without a problem, the price has gone down and most of the Blu-ray players coming out will support upscaling of DVDs to 1080p/1080i, so your existing DVD collection will look even better than before.
If you want to buy blu ray player be careful: Blu-ray Disc players sold in a certain region may only play discs encoded for that region.
Blu ray disks
Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world’s leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson).
Blu-ray is currently supported by more than 180 of the world’s leading consumer electronics, personal computer, recording media,video game and music companies. Blu-ray also has the potential for much higher speeds, as a result of the larger numerical aperture (NA) adopted by Blu-ray Disc.
Blu-ray Disc uses a "blue" (technically violet) laser operating at a wavelength of 405 nm to read and write data.
The direct competitors to this format are both standard DVD and download services. But there are good news for the new comer: Blu-Ray costs production costs are coming down to DVD level much quicker then they would if PS3 games were in DVD.
Blu-ray may be the future for storage that’s both large and fast, but right now it seems shoe-horned into gaming applications.
