[ 14. The Blu-ray Disk Website | Format ]

[ The Blu-ray Disk Website ]

Blu-ray Disk is a next-gen optical disk format that allows for the storage of data, high-def and standard definition digital media and Playstation 3 games. The Blu-ray Disk and player exploits the shorter wavelength of the blue/violet reading laser used to read the “1’s and 0’s”, the grooves on the disk. The much shorter wavelength of Blu-ray reading lasers [ ~ 405nanometres ] allows the “bumps” to be packed more compactly and more densely on the disk itself and this enables a lot more information [ 25GB per layer ] to be stored, just over 5 times the amount stored per layer on a regular red-laser DVD. A 200GB Blu-ray Disk has been manufactured using six 33GB layers, although this disk would almost certainly not work on today’s regular BD Players, which incidentally are also backwards compatible to play DVDs too.

[ In Detail ]
Blu-ray Disk is not aimed at any particular demographic, although the older generation may not be so inclined to convert to the newer technology. To whoever does convert to Blu-ray technology, greater quality of video and audio are granted and much more data can be stored on BD, possibly where DVD had 2 or maybe 3 disk compilations or trilogies, now can all be stored on one disk, eg. the entire Matrix Trilogy could be stored on one disk with space to spare for extra features and other extras. This increases the quality of experience for the audience as it creates less hassle for them. Many institutions have shown their support for Blu-ray Disk, including big names such as Sony, Apple and Fox Entertainment, although the Blu-ray Disk Association including the 9 founders of Blu-ray technology has overall power over the development. BD is in a close format war with HD DVD [ HD DVD ], supported by Microsoft and Intel, as these two essentially identical technologies are mutually incompatible. There are currently over 250 member institutions supporting BD. This convergence of institutions is rather like the consortium including Nokia, Microsoft and Intel for Bluetooth technology begun in 1994.

The progression towards BD allows for a better experience for the audience, they make it more interactive and non-linear, allows more proliferation, miniaturisation, a personalised experience, which is more flexible, better converged and presses for vertical integration with this otherwise incompatible technology.
