Blu-Ray Discs

Has anybody seen these new blu-ray discs yet? They can hold a staggering 25-50 gigabytes but the bad thing is we will need new dvd recorders to use them.

All the company have started making them, but i wonder what the price tag is one of those. Id say it have to be at least over 10 dollars a piece

i haven't seen them yet, but it's like a portable HD. only in cd shape. What do we have to put on that! [:O]

Holy crap 10$ a piece that's a bit tooo expansive i know it's 2 3 gigas but in some year it will cost 1.50 like other 700 mb discs anyway thanks god i have dvd recorder.

I would say they are primarily for DVD use...although most DVD movies are rarely over 2 gigs on a computer. Looks cool though

Blue-ray have been arknown for some time now. But it will stil take a long time before we start seing more of it. Remember dvd used a long time before it realy got big, and I think the dvd-format will still be around for a long time. Also this may not be the next media. The HD-dvd system are also doing nice, and last onth they got support from 4 major hollywood studios.

my cousin was telling about this, It's sounds cool, but anyways, how does it work? I don't feel like following the link.[blah]

Blu-ray Disc

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 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.


Enough for you thecool?

i dont think that they will catch on. too many (over 100 million) red ray discs already used.

matt, will PS3 using Blu-Ray discs?

I wouldnt think so.

Its not a matter of them "Catching on" I think, With all the next-gen DVD Tv recording facilities, I think for some people these will be an absolute life saver. I have a DVD Recorder at home (Not a blue-ray though) and let me tell you, we use at least 5-10 discs a week just recording things. Over 13 hours of standard TV is pretty awesome and with systems like Sky+ catching on, I think they'll be a bigger success than you think.
