		The Advanced Optical Disk (AOD) is similar to the blue ray disk: a CD size (5.25" or 120mm) optical data storage media, that uses a blue laser at 405 nm wavelength.
		The AOD is promoted by Toshiba and NEC and is a direct competitor of the blue ray disk.
		To compensate the lack of storage space (15GB instead of Blue ray disks 25GB) is to be compensated with a better codec, here Windows Media 9 or H.264.

	Blu-ray Disc - Wikipedia, the free encyclopedia
		Blu-ray systems use a "blue" (technically blue-violet) laser operating at a wavelength of 405 nm to read and write data.
		The minimum "spot size" on which a laser can be focused is limited by diffraction, and depends on the wavelength of the light and the numerical aperture of the lens used to focus it.
		The letter "e" was intentionally left out of the name to allow trademarking, as the term "blue ray" is a commonly used phrase and can't be registered as a trademark.

		By this stage the term Digital Versatile Disk was used by some companies to reflect the fact that non-video formats of the disk would also be used.
		There are two successors being developed by two different consortiums: The Blue ray disk and the Advanced Optical Disk.
		On November 19, 2003 the DVD-Forum decided with eight to six votes that the Advanced Optical Disk is the HDTV successor of the DVD.

	Chandra Press Room :: Discovery of Giant X-Ray Disk Sheds Light on Elliptical Galaxies :: December 18, 2002
		The disk, spinning through a distant galaxy, is more than just an interstellar oddity, the researchers say.
		But while its gargantuan scale is striking, the disk also yielded another surprise: The hot gas is not in calm balance with the gravitational forces as expected, but spinning through the galaxy.
		The astronomers hypothesize that the X-ray disk was created during the collision of an elliptical galaxy and a spiral galaxy.

		Hard disk technology was investigated as a possible solution given the ever-increasing cost-effectiveness and ever smaller physical size possibilities.
		While the Blu-ray disk's write data transfer rate is certainly fast enough to record DV compression at 25Mpbs in real time, it appears that a significant drawback would be that studio-quality 50Mpbs data rate recording cannot be accomplished on a consumer-specification Blue-ray disk.
		At least one, perhaps two, additional blue laser-based disk recording formats would need to be developed to record higher quality SD and HD video onto disks.

		Toshiba Corp. used a 15-Gbyte single-layer disk to send data at 36 Mbits/second, in a system that uses a 405-nanometer blue-violet laser with a numerical aperture of 0.65.
		In the proposed specifications, disk capacity is defined as 30 Gbytes for a dual-layer ROM disk and 40 Gbytes for a dual-layer writable disk.
		For a write-once disk, disk giant TDK proposed a disk that uses non-organic recording material — an alloy of silicon and copper.

		The Blue Ray Disk is a storage device from Sony (Product name BDZ-S77), that saves information on a 120mm (5.25") disk (CD/DVD size) with the help of a blue laser of 405nm wavelength.
		According to Philips the blue ray disk (also called blu-ray) can be rotated at 10000 rpm, which will increase the data transfer rate.
		On Sep 1, 2003, JVC and Samsung announced their blue ray products on the IFA in Berlin, Germany.

		Conventional CD-ROM drives may be a part of computers for years to come, just as floppy disks remained a core component of PCs long after their utility diminished; but with disks that can store almost 100 times as much information available, the age of the CD-ROM will inevitably end.
		Because of the materials blue lasers have to be made out of it turns out that they get something like 1/100th of the shelf life of a red laser.
		Blue laser allows between 27 to 35 GB on one layer on one side.

		Analysis of the structure of the disk shows that it is rotating and appears to be cooling.
		The existence of a large, rotating disk of hot gas suggests that NGC 1700 was created by the merger of a rotating spiral galaxy and an elliptical galaxy containing hot gas.

	Sony, Nichia team up on violet lasers (Site not responding. Last check: 2007-10-10)
		Sony is one of the leading promoters of the Blu-ray Disk, a writable optical-disk system that uses a violet laser to realize a DVD capacity of 23 to 27 Gbytes per side.
		Sony sets the target specifications for Blu-ray Disk lasers at 405 nanometers, with output power of 100 mW, to write data to two-layer disks with reliability of more than 5,000 hours.
		In preparation for the coming era of blue-laser optical disks, Sharp Corp., another leading semiconductor laser supplier, has disclosed plans to begin volume production of violet lasers at the end of next year, at a new fab now under construction in Mihara, Japan.

	Macworld: News: High-capacity optical disk format proposed
		Blu-ray disks will be rewritable, 12-centimeter disks and have a data capacity of around 27GB, which is enough for two hours of high-definition digital television.
		Blue lasers have a shorter wavelength -- 405 nanometers compared to around 650 nanometers on DVD systems -- and that means the laser beam can be focused onto a smaller area of the disk surface.
		Some companies want to keep the price of disks low and so propose using cheaper materials that will be able to hold slightly less data while other companies prefer selling more expensive disks that can hold more data, the group said.

		Blue Ray is going to die a slow death unfortunatly.
		This means Blue Ray disk makers will have to charge more for new equipment, which will be passed on to content providers and reflect in higher prices for Blue Ray DVD's.
		Most of that extra space that Blue Ray will provide will most likely be used for crap that nobody watches, like outtakes, lost (ie unecessary) scenes and alternative endings.

		The technique will use ultraviolet lasers, which emit shorter wavelength rays than blue lasers.
		They use the beam to write data holes in a master disk, each separated by 70 nanometres.
		That gives a data rate 20 times more than the blue laser Blue-ray disk.

		The new format is called a Blu-ray Disc because a blue laser is used to read/write, which is able to cram more data onto the discs than the red laser currently used.
		The name is a combination of "Blue" and optical ray "Ray".

		They may impress you tremendously but the folks you wave them in front of may be choking back due criticism of their unpleasant bouquet.
		If this were the case with CD vs DVD, where one could hold many times the data of the other, I might be incline to agree with you (even then, I still keep CDs around for Linux ISOs, and other things that I don't want to waste a more expensive DVD for).

		Toshiba's decision to give way on the disk format was apparently made after examining cost issues related to the Sony technology.
		The HD-DVD format can allow companies that press disks to use a lot of the same equipment they have already, whereas Blu-Ray would mean they have to adopt totally new equipment.
		HD-DVD achieves 45 gigs per disk (which is almost the same as Blu-Ray anyway) by adopting a three layer disk format.

		The dual-layer disk is an effort to realize a 40-Gbyte capacity on each side using technologies similar to that of DVD.
		The AOD system uses an objective lens with a numerical aperture of 0.65 and the same disk structure as DVD disks (two 0.6mm thick platters bonded together).
		The competitive Blue-ray Disk format uses a lens with a numerical aperture of 0.85 and a disk with a 0.1-mm cover layer, which makes the format incompatible with the DVD format.
