Blu Ray discs were introduced in year 2002 when a group of firms announced about this new format of storage over discs. These discs are new standard for storing data over removable disks like CD and DVD. A single layer blu ray disc (BRD) can store up to 25 GB where as double layer disk can store 50 GB of data.
Currently DVD writing is supported by BRD video products. A DVD player can not read BRD as BRD as the pits in BRDs are finer than those of DVDs and as standard follows, BRD drives will be able to play DVDs and CDs.
Data transfer rate in BRDs is 36 Mbps as compared to 10 Mbps of DVDs. As far as recent developments are concerned, JVC has developed a Blu-ray/DVD combo disc with an approximate 33.5-GB capacity.
In these last 6 years, more than 20 big companies have joined the Blu Ray Disc group and have involved in its production. The major companies in this forum are - HP DELL PHILIPS SONY SHARP THOMSON HITACHI TDK APPLE SAMSUNG PANASONIC LG
And the contributors include - Adobe Fuji Photo Film Co. Ltd. Canon Nero LITE-ON IT Corporation Broadcom

As for holding music and videos i would say it does a great job but for games....no way. I did have a case of blue rays and i used them for music and i was able to hold over 70 songs on it, as for movies it may be a little hard to beleave but i was able to hold 2 movies on one disk.
Overall there are really nice for music and movies, as for games they wont be making a lot of money cause their to exspensive.
This is one of the major problems with the new technology, cost. If only these kinds of things weren't that expensive, many people would be using systems like the ps3 which are really expensive.
I'm sure the prices will go down eventually though, once new products are out. I think it's probably just the manufacturers trying to snatch money.
I always did wonder why the backs of some CDs for the Playstation 2 were blue and why some were still regular. Now I finally know it is for more storage. I like the idea of storing that much more data. Of course it is going to cost more though because it holds more which might also mean the game has some extra quality or just more levels who knows. I like the idea of having 2GB in a CD that would be pretty cool, store a bunch of stuff in there.

I'm not trying to crush your post but are you sure thats right, I'm pretty sure that Playstation 2 can't do blu-ray discs, although I was never really sure whether those ones with the purple backing were special in some way!!! I may well be wrong but isn't it just something to make them look nicer.. ( EDIT: Maybe a scratch-resistant coating for those who like to lob their discs around..? ) - just give em a shiny blue coating I don't really like the idea of blu-ray discs because of costs. Much later on though, once thye have dropped it would be worth moving across but DVD-RAM and Dual layer DVD will more than suffice for me at the moment it just doesn't seem worth the hassle to go converting every product / computer / DVD player with a disc drive to be able to read - letalone write those discs...
Yes, Sony took over BlueRay for there console, Playstation 3. I think it is quite useful having 50 - 60 GB disk to hold the PS3 games, but I don't like to look of the price. But we'll have to wait and see what Sony do about it.
It is true that the prices will eventually fall. In the manufacturing industry, the higher the demand, the lower the prices will get. So hold on guys and gals, just be patient and wait out.
I think BlueRay is becoming more and more needed considering computers nowadays are going way past gigabytes and just about going over terabytes. Its essential to have a high-capacity medium for your backups.
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 the world's leading consumer electronics, personal computer and media manufacturers (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. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.
While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on 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 with CDs and DVDs through the use of a BD/DVD/CD compatible optical pickup unit. 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.
Blu-ray is currently supported by more than 170 of the world's leading consumer electronics, personal computer, recording media, video game and music companies. The format also has broad support from the major movie studios as a successor to today's DVD format. Seven of the eight major movie studios have already announced titles for Blu-ray, including Warner, Paramount, Fox, Disney, Sony, MGM and Lionsgate. The initial line-up is expected to consist of over 100 titles and include recent hits as well as classics such as Batman Begins, Desperado, Fantastic Four, Fifth Element, Hero, Ice Age, Kill Bill, Lethal Weapon, Mission Impossible, Ocean's Twelve, Pirates of the Caribbean, Reservoir Dogs, Robocop, and The Matrix. Many studios have also announced that they will begin releasing new feature films on Blu-ray Disc day-and-date with DVD, as well as a continuous slate of catalog titles every month.

All new products start out really really expensive especially technology as significant as this. Did you notice the price of DVD's and their players when they first came out? Trust me these will slowly lower in price. And no Playstation shouldn't have just gone with dvd's when blu ray gets cheaper and everyone has it, everyone would have yelled at sony for not putting it in their machine.
The question isn't blu ray or no blu ray, the question is blu ray or HD Dvd. One of them is certainly going to win, the question is which one. Different movie companies are going for different formats. It's the whole 8-track vs. tape thing all over again...
Someone asked me about Blu-Ray and this is what I told him:
QUOTE
Blu-Ray discs are a new and improved technology that is capable of storing up to 50GB or so on a single disc, making them much better in the capacity sense than a conventional DVD or even a dual-layered disc. In THEORY, I would imagine that this would allow less compression and more raw video content, resulting in better quality, more features, and less restrictions on what can be included in a single disc.
It was a moderate amount of reading, but very interesting. Blu-Ray gets its name from the fact that the laser used to etch data onto the disk is blue (having a shorter wavelength than the red lasers they use for CDs and DVDs). I was correct about data capacity being up to 50GB, which equates to about 9 hours of high-definition video or 25 hours of normal video. It supports the usual codecs for movies and whatnot; however, this doesn't mean that it's limited to it.
Blu-Ray is currently in competition with HD DVD discs in a sort of storage media "war, " trying to oust the DVD format. Blu-Ray has one thing really going against it: the fact that mass production may NOT be cost-effective. (When will we be watching 9 hr HD movies?) HD DVD is cheaper, but falls short to the Blu-Ray with just 15-25GB of storage.
I would imagine that both storage formats would find a niche in today's advancement in technology. If I had my say, HD DVD should take over the standard for DVD movies and such, and Blu-Ray should take a hike for a little bit from the entertainment department, instead focusing on creating another storage means for PC users until we develop better codecs that allow even less quality to be compromised when writing to one of these discs.
I saw a comparison between hd dvds and blueray discs and the blue ray disc won on audio quality while the hd dvd beat the blue ray disc in video and speed. I really hate that there will be 2 new digital formats.
As i have heard many things about blue ray discs and many people don't think they are going to last. Whenever sony comes out with their own format it always seems to be beat out by the original. But i guess we will just have to wait and see.
Using RAID can improve performance or security of data and data transfer on any computer (that has
drives that support). RAID is a system for sharing or duplicating data among various harddisks.
Depending on which level one sets RAID up a person can get increased data integrity,
fault-tolerence, and/or capactity than single disk drives. RAID also makes the computer see multiple
drives as one logical drive. RAID is typically used on servers, either to provide more efficiency or
to backup all data. The most common levels of RAID are 0 and 1. RAID 0: This level is usuall....
