I was reading an article today and compared it to an article I saw a while ago and I think this is odd.

Sony has confirmed the Plastation 3 will use Blue-Ray discs which are the same size as a standard CD/DVD, but are read with a blue laser and can hold 23GB of data on 1 layer, 46GB on two, but Microsoft has stated that the next generation Xbox (Xenon) will use the standard DVD format which can only hold 4.4GB on 1 layer, 8.8GB on two.


I tell you now - if PS3 has a disc with 46GB of max data and the Xenon has one with a max of 8.8 then I'm going with the PS3 - no doubt!

IMHO DVD is a big mistake on Microsoft's part.

Isn't 8.8 gigabytes enough?

It is for todays games, but think what you could do with 46!

You could have games that would almost never end!
MMOG with every city on earth!

Blu-Ray Disks are DVDs. :\

Yeah once i thought about a game like that.. GTA style OMG it would RULE!..

I dont think ill be buying the PS3 once i get the PSP ill just concentrate in it.. maybe a PS3 one day...ill think about it later but yeah 46GB is much better than 8.8. a lot more possibilities

What i dont like is that plastic supports like the UMD has...

No it is not. CDs and DVDs are read with a red laser, Blue Ray discs are read with a blue laser and can store BOATLOADS more data.

<b>What is Blu-ray?</b>

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 leading consumer electronics and PC companies (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. A single-layer Blu-ray Disc can hold 25GB, which can be used to record over 2 hours of HDTV or more than 13 hours of standard-definition TV. There are also dual-layer versions of the discs that can hold 50GB.

While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM use a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible through the use of a BD/DVD/CD compatible optical pickup and allow playback of CDs and DVDs. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB.

With the rapid growth of HDTV, the consumer demand for recording HD programming is quickly rising. Blu-ray was designed with this application in mind and supports direct recording of the MPEG-2 TS (Transport Stream) used by digital broadcasts, which makes it highly compatible with global standards for digital TV. This means that HDTV broadcasts can be recorded directly to the disc without any quality loss or extra processing. To handle the increased amount of data required for HD, Blu-ray employs a 36Mbps data transfer rate, which is more than enough to record and playback HDTV while maintaining the original picture quality. In addition, by fully utilizing an optical disc's random accessing features, it's possible to playback video on a disc while simultaneously recording HD video.

Blu-ray is expected to replace VCRs and DVD recorders over the coming years, with the transition to HDTV. The format is also likely to become a standard for PC data storage and HD movies in the future.

So in the future we are going to have Gama-ray disks?

0.001 nm well... lets make the math.

Dual Layer blu ray disks.
405 nm -------------- 50 GB
0.001 nm ------------ x.

x= 50*0.001/405 = 1.235x10 to the power of -4

Erm..  idont know whats wrong.. lol maybe lets make a stupid thing and : 50 x 405 / 0.001 = 20250000 Gbytes? Maybe its my math that is all forked up.. i dont know why it didnt work well.. maybe because its inverse porpotion ?.. oh well its just the sleep then

is that 6TB, 6PB or 6EB?

I searched and it says 500 petabytes.. so.. i think my math is really bad then

* Look at the first comment

I doubt that games are mainly limited by how much you can fit on a disc... who's gonna program and design enough stuff to fill 46 GB?
