Found some data on blu-ray

It's a pdf file



and if this has been posted before, i dont care, so save the typing

Good find now we know that the blue ray disk is done, i like the specs

[Coryphaeus]

The last part, "recordable optical pickup head" does that mean read write will be going right out the door from day one, maybe even on the ps3?

[Aleman]

The PS3 will have a read-only Blu-ray drive.

Well Blu-ray discs have been out for a while now in Japan. I think it is the DL Blu-ray Discs (50GB) that have been recently completed or have been being mass produced. Panasonic claims that they're already manufacturing Blu-ray discs in Cali.

It has been out in Taiwan since 2001 ... they were using it to back hard-drives

[henning]

Yeah, but the Blu-ray that has been availale up until now is a slightly different version. I don't even know if they're compatible.

[PeanutButterMunky]

This is in the wrong section.

Blu-ray Disc (BD) is a next-generation optical disc format meant for storage of high-definition video and high-density data. The Blu-ray standard was jointly developed by a group of consumer electronics and PC companies called the Blu-ray Disc Association (BDA). As compared to the HD DVD format, its main competitor, Blu-ray has more information capacity per layer, 25 instead of 15 gigabytes, but may initially be more expensive to support.

Blu-ray gets its name from the shorter wavelength (405 nm) of a "blue" (technically blue-violet) laser that allows it to store substantially more data than a DVD, which has the same physical dimensions but uses a longer wavelength (650 nm) red laser.

Blu-ray have said that their plans for a Spring 2006 launch will be unveiled at the Consumer Electronics Show (CES) in January

single-layer Blu-ray disc (BD) can fit 23.3, 25, or 27 GB; this is enough for approximately four hours of high-definition video with audio. A dual-layer BD can fit 46.6, 50, or 54 GB, enough for approximately eight hours of HD video. Capacities of 100 GB and 200 GB, using four and eight layers respectively, are currently being researched; TDK has already announced a prototype four-layer 100 GB disc. [2]

The BD-RE (rewritable) standard is available, along with the BD-R (recordable) and BD-ROM formats, which became available in mid-2004, as part of version 2.0 of the Blu-ray specifications. BD-ROM pre-recorded media are to be available by early 2006.

Also, in addition to 12 cm discs, an 8 cm variation for use with camcorders is planned that will have a capacity of 15 GB. [3]

To ensure that the Blu-ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB–200GB (25GB per layer) in the future simply by adding more layers to the discs.

Blu-ray systems use a "blue" (technically blue-violet) laser operating at a wavelength of 405 nm to read and write data. Conventional DVDs and CDs use red and infrared lasers at 650 nm and 780 nm respectively.

The blue-violet laser's shorter wavelength makes it possible to store more information on a 12 cm CD/DVD sized disc. 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. By decreasing the wavelength, using a higher numerical aperture (0.85, compared with 0.6 for DVD), higher quality, dual-lens system, and making the cover layer thinner to avoid unwanted optical effects, the laser beam can be focused much more tightly at the disk surface. This produces a smaller spot on the disc and allows more information to be physically contained in the same area. In addition to the optical improvements, Blu-ray Discs feature improvements in data encoding, allowing for even more data to be packed in. (See compact disc for information on optical discs' physical structure.)

While it is not compulsory for manufacturers, the Blu-ray Disc Association recommends that Blu-ray drives should be capable of reading DVDs, ensuring backward compatibility.

JVC has developed a three layer technology that allows putting both standard-definition DVD data and HD data on a BD/DVD combo disc. If successfully commercialized, this would enable the consumer to purchase a disc which could be played on current DVD players, and reveal its HD version when played on a new BD player.

the ps3 is going to kill the 360 because of this

[bosbeest]

yeah well blu-ray is the future for all disc using machines. It was a stupid move on MS' side not to use it.

But it's strange, cuz, Philips electronics developed the Blu-ray, and now sony is using it?

Philips Electronics, a world leader in optical storage and a founding member of the Blu-ray Disc Association, will be revealing its prototype all-in-one PC writer that reads and writes CD, DVD and Blu-ray Discs. The demonstration will be held on the Philips booth #9004 at the CES 2005 exhibition. The introduction of this unique all-in-one PC writer is scheduled for the second half of 2005.

The PC drive utilizes Philips' latest compact OPU81 triple-laser optical pick-up unit in which separate infra-red, red and blue lasers share the same optical pathway to provide Blu-ray Disc read/write capabilities as well as read/write compatibility with DVD and CD. This compact optical pick-up unit is based on a flexible architecture, allowing future speed improvements to be easily and cost-effectively implemented.

"With the introduction of this new product concept we have created the ultimate consumer product" said Cor Saris , CEO of Philips Optical Storage. " Combining the success of CD and DVD Recording with the BluRay Recording formats into one PC writer will accelerate the acceptance of this new format in the PC and Consumer market."

Blu-ray Disc is the most advanced new optical storage standard that will satisfy all next-generation requirements in terms of storage capacity, data speeds, copy protection, interactivity, convenience and cost. As consumers worldwide gain access to high-definition TV (HDTV) through cable, satellite and terrestrial channels, they are not going to be satisfied with less than equal quality in their video recordings. Blu-ray Disc is the only format with the capacity of 25 Gbytes on a single-layer disc and 50 Gbytes on a dual layer disc, to offer full-length feature movie playback using high-definition MPEG2 encoding - the native compression technique for HDTV broadcasts - or even more with advanced codecs, like AVC. In addition, for pre-recorded packaged media, Blu-ray Disc has sufficient capacity to include bonus materials and interactive sessions for an unparalleled entertainment experience. For PC users archiving photographs or video and other data on the hard disk, Blu-ray Disc is the only recordable/re-writable format that provides such a quantum leap in optical storage capacity and gives a seamless experience between PC and CE environments.

Philips is yet again at the forefront of supporting the establishment of Blu-ray Disc as the ultimate long-lasting standard that will take the industry forward in a quantum leap instead of a succession of incremental and consumer confusing steps.

Promoted by the world's leading consumer electronics, PC, disc replication manufacturers and movie studios, the global standardization activity for Blu-ray Disc has already attracted a total membership of more than 90 companies to the Blu-ray Disc Association (BDA). The BDA includes companies from every part of the value chain in high quality video and multi-media delivery.


I don't get it

Square-Enix has shed some light on the delay behind the PlayStation 3 version of The Last Remnant, revealing that the highly anticipated RPG was pushed back mainly due to “development reasons” attributed to the Unreal Engine.

When asked on the reasons behind the game’s delay, members of the Last Remnant Team told Gamespy, “This is mainly for development reasons,” adding, “We're developing the game using the middleware Unreal Engine, and the Unreal Engine has a slower development on the PS3 side.”

“It was only really workable after Unreal Tournament was published, so this was mainly a development decision,” the team added.

The Last Remnant will be coming to the Xbox 360 first as a timed exclusive, with the PS3 version following some time after.

Players assume the role of an 18 year-old swordsman named Rush Skyes, who embarks on a mission to rescue his sister, Irina, ultimately ending up in the middle of a global conflict surrounding a series of powerful artefacts known as remnants.

In terms of content, director Hiroshi Takai has revealed that the game will incorporate a brand new combat system, referred to as a "Turn-burst, command-based system using symbol encounters,” as well as various Quick Time Events (QTEs)

Stay tuned.
