Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage media format. It is mainly used in high-definition video and data storage. Blu-ray Disc has the same physical dimensions as a standard DVD or CD.

A single-Layer Blu-ray has storage capacity of 25GB, while a dual-layer BD can store up to 50GB of data. As the name suggests, a blue-violet laser is used to write data on a Blu-ray disk, unlike the traditional method wherein red laser employed to store data on DVDs.

A Blu-ray disk can hold 9-hour high definition video and standard-definition (SD) video that can run 23 hours, on a 50GB disk. The BD-ROM movies will require a rate of MBPS for data transfer, so the expected speed is 2x (72 Mbps). There is also a scope for having much higher speed because of the larger numerical aperture (NA) adopted by the BD. It implies that a Blu-ray disk will need less recording power and lower disk rotation speed vis-à-vis conventional DVDs and HD DVDs. The sole limiting factor for blu-ray is the capacity of the hardware.

The storage capacity of Blu-ray disk (BDs) is five times that of conventional DVDs. BDs supports NPEG-2, MPEG-4 AVC and SMPTE VC-1 formats (codecs).

Blu-ray Disc uses a “blue” (technically violet) laser operating at a wavelength of 405 nm to read and write data. Conventional DVDs and CDs use red and near 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, increasing the numerical aperture from 0.60 to 0.85 and making the cover layer thinner to avoid unwanted optical effects, the laser beam can be focused to a smaller spot. This allows more information to be stored in the same area. For Blu-ray Disc, the spot size is 580 nm In addition to the optical improvements; Blu-ray Discs feature improvements in data encoding that further increase the capacity.

Technology has come a very long way of the past years and has altered the method in which people vie their movies. You can probably remember the days when people watched their home movies through their VCR’s. Of course these VHS tapes were bulky, consumer a lot of storage room, and output much lower quality visuals than seen today with DVD’s and the emerging BD media. LaserDiscs’s soon thereafter replaced the VHS and VCD’s but this was short-lived when DVD was introduced to the scene. DVD (Digital Versatile Disc) was of course much more advanced than VCD and stored six times more information.

A single DVD with a storage capacity of 4.7 GB is capable of storing one full-length movie as well as other behind-the-scene footages and other extra features. Due to this, DVD’s have had a major impact on the movie industry and as a result a greater number of people are purchasing DVD’s to view in their homes. The DVD may however be replaced by a new technology that would further enhance the movie industry. This new technology is known as Blu-Ray.

Blu-Ray technology is considered to be the next-generation DVD. Blu-Ray Discs or BD can record, store and are able to play back more video, digital audio, as well as computer data. BDs can also store a full length high-definition movie which usually takes a higher bandwidth and storage space. Compared to DVDs. Blu-Ray Discs have the advantage on the amount of information that it can store. A single-layer BD has the capacity to store 27 GB of digital information. This single-layer BD is enough to hold more than two hours of high-definition videos or to hold more than 13 hours of standard video. A double-layer BD on the other hand can be able to store more than 4.5 hours of high-definition video because of its 50 GB storage capacity.

Laser lights are effectively the way in which optical disc storage media (for example DVD and Blu-ray) are able to read information, with Blu-ray utilizing blue violet rays whereas DVD uses red ultraviolet rays. The amount of information that can be stored in discs is dependent on how large and precise the laser light is. Blue laser has a shorter wavelength than that of red laser and because of this, blue laser is more precise and can write information in much smaller spaces. This is the reason why a lot more information can be stored in a Blu-Ray disc.

A huge storage capacity is not the only advantage of a Blu-Ray technology. Blu-Ray Discs can also transfer information at a higher rate. Blu-ray discs are so revolutionary because they are capable of a data transfer rate of 36 Mbps (megabits per second) whereas a standard DVD can only transfer at a rate of 10 Mbps.

Two technologies namely, Blu-ray and High Definition DVD (HD-DVD)are competing against each other to successfully become the official storage medium for the future of high definition media. Blu-Ray discs were first utilized by Sony in their PlayStation 3 games and because of this, BD is now becoming popular among giant movie production studios such as Warner Brothers which have stated that they will only release their High Definition movies in BD formats starting May of 2008.

Blu-ray is capable of storing and playing movies in 1080p resolution. In many respects, 1080p resolution is called “True High-Definition” or “Full High-Definition”. A Blu-ray disc can store and play roughly around 5 to 6 hours of high-definition content (1080p resolution) and around 24 hours of standard-definition content (480i or 480p resolution). With the capability of storing up to 50 gigabytes of data, you will be able to watch an entire Blu-ray movie with crisp clarity.

But what exactly is 1080p resolution?

Well, the number 1080 means that there are 1,080 lines of vertical resolution. Generally the larger number of vertical resolution lines, the sharper and more detailed the image. The letter “p” stands for progressive scan. Progressive scan (a.k.a. non-interlaced) is a way to transmit, store, or display moving images. The other method of transmitting, storing, or displaying moving images is called interlace. Interlace is represented by the letter “i” (1080i). Interlace was created to improve video quality without consuming more bandwidth. However, progression scan is superior to the interlaced method because the progression scan method transmits, stores, or displaying moving images by processing all horizontal lines sequentially each frame. While the interlace method processes every other line in one frame, then the rest of the lines in the next. This results in reduced horizontal resolution. While the interlace method isn’t all bad, and the progressive scan method isn’t prefect, when it comes to which provides the best picture quality, progressive scan is the way to go.

HD DVD has the capability to store and play movies in 1080p, so why is Blu-ray better?

The answer to that question requires one word, space. A HD DVD has greater limitations than Blu-ray. HD DVD discs and Blu-ray discs come in two forms, single layered and dual layered. Please note that the higher the number of gigabytes, the more data that can be stored. A single layered HD DVD disc has a maximum capacity of 15 gigabytes and a single layered Blu-ray disc has a maximum capacity of 25 gigabytes. When these two discs are dual layered, their maximum capacities are doubled, with a HD DVD at 30 gigabytes and Blu-ray at 50. So, at most Blu-ray can handle 20 gigabytes of additional storage, and with a world that is constantly changing, that extra 20 gigabytes can make a world of difference.

Blu-ray movies: In the highest definition ever!

Blu-ray movies have the edge over HD DVD movies. Due to the lack of space, HD DVD will eventually fall further and further behind. On the contrary, Blu-ray will reach its full potential, being able to store more of the finest details and stunning visuals. Blu-ray has reached the highest definition ever!

Blu-ray and Blu-ray Movies has reached the highest definition ever.

DVDs continue to be the prominent medium for home theater entertainment. The technology is being refined and improved upon by a number of manufacturers, making its future slightly uncertain though it is definitely clear that it will continue is one format or another. Many of you have probably been hearing about Blu-ray and HD-DVD discs and their path as the next generation of DVDs. The discrepancies between the two are confusing many home theater buyers, so it’s important to know just what each of these new technologies has to offer so that you can make an informed decision on what to purchase and when.

Let’s start by discussing just what Blu-ray is. Chances are, if you’ve stepped into any of the leading home theater and electronics stores in the country, you’ve seen Blu-ray discs advertised in the DVD section. In truth, Blu-ray discs are somewhat like traditional DVDs, except that they have the ability to record, rewrite, and playback high definition (HD) video that is compatible with the growing number of HD televisions finding their way into home theaters every year. Unlike traditional DVDs, Blu-ray discs can hold nearly five times as much data. On a single layer disc, they can hold 25GB of data, and 50GB can be stored on a dual layer disc. By being able to hold so much more, Blu-ray discs are able to easily store the advanced information necessary to provide content in HD format.

HD-DVD offers the same technology, though it isn’t able to hold as much information as Blu-ray. Developed by Toshiba and NEC, it is able to hold three times as much data as traditional DVDs. While this may be less than Blu-ray, the data capacity of HD-DVDs still exceeds the amount needed to watch major blockbusters in high-definition. HD-DVD also came out much sooner and was first quoted to be the successor to the standard DVD format. HD-DVD is completely compatible with HD-DVD players, which in turn are compatible with HD televisions. High definition technology is certainly the wave of the future for home entertainment, and HD-DVD was the first disc technology formatted for it.

Both Blu-ray and HD-DVD discs use a new form of laser that improves on what the standard DVD used. While older, standard DVD models used a red laser to transfer content from disc to player to screen, these two technologies use a blue-violet laser instead. The main benefit with using blue-violet lasers is that they have a shorter wavelength than red lasers. This means that they can be focused with a much higher rate of accuracy.

As you can see the differences between these two formats are very few, In short, Blu-ray is able to hold more information than HD-DVD, but HD-DVD has been around for much longer and still holds an adequate amount for any applications currently in the market. Both formats use blue-violet lasers to better read the information.

The biggest question right now is which format will end up on top. Blu-ray has the added advantage of being backed up by some major players in the movie business. Seven of the eight major Hollywood movie studios have released films in Blu-ray format recently, while five of them are releasing films exclusively on Blu-ray. HD-DVD has the backing of several major consumer electronics manufacturers but does have some ground to make up with the production companies. However, with the added experience of being in production longer and having consumers more familiar with the name, it’s very possible for them to pull ahead. The race to be the top home entertainment format will continue on and the consumer will simply need to wait to see which one wins. In the meantime, players are available for both formats and some manufacturers have players that satisfy both formats available.

Warner Bros. has announced that they will be supporting Blu-ray exclusively. The decision, according to their statement, was chiefly because of strong consumer liking for the format.

“In response to consumer demand, Warner Bros. Entertainment will release its high-definition DVD titles exclusively in the Blu-ray disc format beginning later this year, it was announced today by Barry Meyer, Chairman & CEO, Warner Bros. and Kevin Tsujihara, President, Warner Bros. Home Entertainment Group.

“Warner Bros.’ move to exclusively release in the Blu-ray disc format is a strategic decision focused on the long term and the most direct way to give consumers what they want,” said Meyer. “The window of opportunity for high-definition DVD could be missed if format confusion continues to linger. We believe that exclusively distributing in Blu-ray will further the potential for mass market success and ultimately benefit retailers, producers, and most importantly, consumers.”

Variety is reporting that Warner sister company New Line has announced that it too plans to shift to Blu-ray exclusivity. For the moment both Warner Bros. subsidiaries, HBO and New Line, remain format-agnostic, though it’s widely expected that they will follow Warner Home Entertainment’s exclusive use of the Blu-ray format. However, the studio’s declaration that it would drop HD DVD support does not extend to titles released by New Line, HBO or the BBC, according to Warner Home Entertainment President Kevin Tsujihara.

Blu-ray is a high-density optical disc format for the storage of digital information, including high-definition video. The name “Blu-ray” is derived from the blue-violet laser used to read and write this type of disc. The Blu-Ray Disc Association, a group of leading companies representing consumer electronics, computer hardware, and motion picture production, developed the format.

Warner Bros.’ decision is a huge development in the Blu-ray disc versus HD DVD format war currently raging on because Warner Bros. was always considered the big fish to be landed by one side or the other. Consumers were lobbied hard by both sides during Christmas as dirt-cheap Toshiba HD DVD players were advertised heavily by Wal-Mart for $98.97 while the higher priced Blu-ray players were also discounted by electronics retailers (though not nearly as much).

The change will take effect from May 2008. Executives at Warner Bros. explained that the choice to solely support one high-definition format over another was made to avoid uncertainty on the market of HD movies and allow Warner’s partners among retailers to stock more titles by Warner than previously. Warner Bros.’ move to exclusively release in the Blu-ray disc format is a tactical decision focused on the long term and the most direct way to give consumers what they want.

Tsujihara says the studio took no pay-offs to exclusively back Blu-ray. He emphatically denied reports that the studio had received anywhere from $250 to $500 million in exchange for dropping its HD DVD format support in a post-announcement conference call. Warner’s only incentive to drop its HD DVD format, according to the exec, was to ensure growth of the “category” and the long-term health of the industry.

Many people are curious as to whether this new technology is worth their hard-earned money. They are looking to see what the true differences are between Blu-ray and standard DVD’s. People want to know what else Blu-Ray offers than just higher definition and clarity.

So what is this whole Blu-ray about, 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.

Blu-ray technology is here to stay. People have been very impressed with this new product and what it offers. They are in love with the high quality and will tell you they wouldn’t choose a regular DVD over it.

This technology with the enhance HD features developing everyday will bring the ultimate home theater experience. This type of technology is no doubt the wave of the future and many accepting this technology into their homes.

There is one complaint about this new Blu-ray technology though. There is not a large enough movie collection out in Blu-ray yet. New releases come out in this way but the older movies that are already out aren’t available. What do you do when you want to see an older movie but it’s not in Blu-ray?

Go out and see what this Blu-ray technology is all about if this interests you. There is a likely chance you will find it amazing. There are so many options like even writing your own materials onto blank Blu-ray discs. This extra capacity combined with the use of advanced video and audio will offer consumers an unprecedented HD experience.

In fact, seven of the eight major movie studios (Disney, Fox, Warner, Paramount, Sony, Lionsgate and MGM) have released movies in the Blu-ray format and six of them (Disney, Fox, Sony, Warner, Lionsgate and MGM) are releasing their movies exclusively in the Blu-ray format.

As you can see a lot of big players in the industry are making the transition. This is becoming a fast transition so this type of technology is never to early to start in one’s life.

Besides being able to play games that date back generations, to games that are the most technologically advance with 1080p high-definition, the Playstation 3 serves another function and another purpose. A purpose that’s worth its weight in gold.
The Sony Playstation 3 is a Blu-ray Player!

But how does the Playstation 3 compare to a standard Blu-ray Player?

The Playstation 3, compared to a stand alone Blu-ray player, has one massive advantage. Price! A standard Blu-ray player can cost anywhere around $850 dollars to a whopping $1,300 dollars. It is obvious that the average person won’t be able to afford such a steep price. Here is one reason why the Playstation 3 comes into its own. Priced at $499 dollars to $599 dollars, the Playstation 3 is by far the cheapest and most affordable Blu-ray player to date. Allowing a boarder audience to enjoy high-definition Blu-ray movies from the comfort of their homes.

What about quality, functionality and is the Playstation 3 easy to use as a Blu-ray Player?

With some of the more state of the art technologies, the Playstation 3 could be considered better than all the Blu-ray players on the market today. From the moment you turn it on and insert a Blu-ray movie via the front loading disc drive, you will be blown away and surprised at the picture quality this little box provides. On average the Playstation 3 turns on and loads up a Blu-ray movie in about 22 seconds, which is highly impressive. Using the wireless gaming control or the soon to be released Playstation 3 remote controller, navigating throughout the Blu-ray movies enjoyable and easy to learn.

Playstation 3: The Blu-ray Player

Sony has made a wise decision to integrate Blu-ray into their system. The Playstation 3 is hundreds of dollars cheaper even if you decide to purchase Sony Playstation 3 remote also, which is estimated to cost around $30 dollars. Even before the release of the Playstation 3, Blu-ray movie sales continued to increase as time goes on. Playstation 3 is the total package, so go out and get one.

Blu-ray Disc: New storage technology

The currently DVD and CD technologies used red laser to stored and reading data that it have 650 nanometer and 780 nanometer wavelength of DVD and CD. But the new technology to store and reading data to DVD and CD developed by Sony and Phillips have only 405 nanometer wavelength. Blu-ray, blue laser technology in storing and reading data is an optical storage format created to store large amounts of high definition video and sound. The color of the laser is a hue of blue-violet and has a shorter wavelength than the red lasers.

The benefits of Blu-ray technology compare with the normal red lasers used today besides the shorter wavelength is capable of storing a much larger amount of data using the same space and also can be read to give a clearer picture with more color and vividness.

The reason to support the above benefits is because the blue laser required a smaller spot size. The wavelength of blue-violet laser uses a 0.85nm pickup aperture. Because of the extreme density of these optical discs, it can fit a large data onto the disc such as 23.3GB of data onto single-layer Blu-ray disc and 46.6GB onto dual-layer Blu-ray disc.

Deplorable condition of Blu-ray technology is it is easy to contaminate by only scratch because of so close together of data. And the really disadvantages of these technology is the Blu-ray disc are so expensive (about the $1,000).

Blu-ray is a new release technology of the electronics market compete with HD DVD’s and looking to make for the PlayStation of Sony. Sony will include the basic Blu-ray disc player with the PlayStation3 as a standard. But the Blu-ray disc is more expensive than the standard DVD counterparts. Therefore the both of two media type must to fight to be a winner. However, the Blu-ray disc need to develop about the way to prevent the scratching of the disc or difficult to scratch for easiness competition. But another reason will make Blu-ray disc have a trouble is it has been developed in part with Sony and Sony also has digital rights management (DRM) that will make the user more difficult to place shift and time shift their content. Now the people are waiting to see who is the winner between Blu-ray and HD.
