| Who Started Blu-Ray?
Blu-Ray discs, owned by Sony, are an improvement upon any of the optical discs of the past. It showcases the capability to store an amazing 25 GB per layer. To set the framework for you, a DVD will hold 4.7 GB per layer. Several manufacturers are already releasing a single layer 25 GB disc, and a dual layer 50 GB disc.What blu-ray discs use is a blue light laser operating at a wavelength of 405nm. Blu–ray is similar to another Sony optical disc product released in 2004, PDD. However blu-ray discs perform at higher transfer speeds.PDD was never intended for home use, it was designed for business data, and backup related purposes.
Another benefit of what blu-ray discs can do is being produced in a protective hard coating technology. Of the major manufacturers producing blu-ray discs each are using there own proprietary coating technology. These companies are Sony, Panasonic, TDK, Samsung, and Verbatim. TDK specifically is testing if the cost is feasible to use there polymer based “Durabis” coating.
Blu-ray is in an infant stage right now but the technology is very advanced. The companies involved are still building upon and advancing this technology. Sony partnering with Toppan printing, a Japanese based paper company has developed a paper based blu-ray disc. This disc would actually contain 51% paper, and still store 25 GB of data. It is being developed for environmental reasons. Other developments are in the works, as these companies work to advance the potential of this technology. Quad Layer 100 GB discs are ready to be released. TDK itself, consistently are improving the technology and have a prototype of a 6 layered 200 gigabyte model. Blu-Ray has a modest amount of support in the corporate world.

Brand Names such as HP, Apple, Dell and Panasonic are just a few of the large companies supporting this new technology. Blu-ray discs primary rival is HD-DVD. Toshiba, The NEC Corporation, Microsoft, and Intel champion the HD-DVD format. Side by side they test quite the same with the differences being; what blu-ray has is a larger capacity, and requires a hard coating. Blu-ray discs transfer at a slightly higher rate, while HD-DVD codec base currently is more versatile. Four studios use blu-ray discs exclusively: Columbia Pictures, MGM, Disney and 20th Century Fox. Sony owns Columbia Pictures and MGM. Three studios are using both Blu-ray and HD DVD: Paramount Pictures, Warner Bros, and New Line Cinemas. Universal Studios and the Weinstein Company, only support HD DVD. Home videos released on the blu-ray format are 50GB dual layer. This is the equivalent of 9 hours of HD video. Home videos released on the HD-DVD format are 30GB dual layer.
These discs only have a 5.4-hour playtime for HD video.Blu-ray discs have an experimental digital right management feature called BD+. This innovative technology can dynamically change the keys for cryptographic protection. What this means is if the keys in use are cracked or found out, manufacturers can update them and update all the discs after that without endangering the whole batch of discs. There is also a managed copy system, allowing users to only copy content a specified amount of times.
Final Thought
Movies, Games, even close to decade’s worth of your favorite music, could fit on a single disc. Large groups of major companies are coming out with a wide assortment of players, burners, discs and other groups of companies are delivering the content for these discs. No matter what the application, blu-ray discs have proven themselves to be a new technology that is here to stay.

Blu-Ray or DVD?Blu-ray is a new high density optical disc format that surpasses established DVD technology in several ways. Blu-ray discs can hold more data, and have faster transfer speeds than DVDs. This gives them the ability to store high-definition audio and visual files. The typical CD can hold 650 MB of data, and the typical DVD can hold 6.7 GB. A single-layer Blu-ray disc holds 27 GB of data, and a double-layer Blu-ray disc holds 54 GB. To understand how Blu-ray technology can surpass DVD material capacity by such a significant amount, it is essential to know how disc technology works in the first place. Surprisingly, modern disc technology has its roots in the record playing, which originated in the mid 1800’s. Records worked through grooves on which a needle ran across, thus producing sounds based on the modulations in the grooves. Put very simply the grooves held information, and the needle retrieved the information.
Laser disc technology works much the same way. DVD technology utilizes red lasers with a 650 nanometer wavelength to read information stored between two polycarbonate layers. Blu-ray technology expands on this capability by using blue-violet lasers (thus the name Blu-ray). Blue-violet lasers have a wavelength of 405 nm, which is significantly shorter than the red laser wavelength, therefore permitting Blu-ray lasers more precision and accuracy. They can essentially read grooves that are twice as small as those on a DVD. In addition, Blu-ray discs store data on top of a 1.1 mm polycarbonate layer, rather than between two polycarbonate layers. This disc design reduces the chances that the laser light will diffuse and cause data retrieval problems.Blu-ray technology has been controversial because of the cost and the competition from rivals like HD DVD technology.
The Blu-Ray Disc Association (BDA) is responsible for its development. BDA has many influential members including Apple, Dell, HP, Sharp, Mitsubishi, and LG. The film industry also has a lot to benefit from Blu-ray disc technology, because it allows films to be recorded on a high-definition capable medium. The studios of Disney, MGM, Lionsgate, Sony, and Fox all release movies exclusively in the Blu-ray format. Sony is another major supporter of Blu-ray technology. The company has invested in Blu-ray for their newest entertainment console, the Playstation 3. Playstation 3’s utilize Blu-ray discs for their media format because of the technology’s many attributes. These include a pristine picture quality, massive storage capability, and a high-definition medium. As a result, Playstation 3 owners enjoy longer game play, and true HD output on the most affordable Blu-ray disc player on the market. Other Blu-ray disc player models cost upwards of $1,000, but the Playstation 3’s price is about $600.Why would anybody pay that much money for a data storage technology? The roots are based in the technology of television signals.
A standard analogue television encodes audio and visual material using an analogue signal by varying the signal’s amplitude and frequency. Every second, 29.97 complete frames are “drawn” on the TV. This signal method can result in flickering, shimmering, or misalignments of the video image. The next step up from analogue is 1080i. 1080i technology consists of 1,080 vertical pixels by 1,920 horizontal pixels which are interlaced together, usually at an aspect ratio of 16:9. Visual data is sent at a rate of 60 interlaced frames per second, resulting in 30 complete frames per second. The result is less flicker, improved details, and a reduction in bandwidth requirements by 50%. This is one type of high definition television, but it is surpassed by 1080p technology. 1080p is the progressive version of 1080i.
1080p has the same pixel resolution, but rather than having interlaced pixels, the picture is sent at 60 complete frames per second. The technology works on the newer LCD and plasma screen televisions, but some of these sets are not equipped to receive outside 1080p signals. It is necessary to convert 1080i signals to 1080p signals, which is feasible since all 1080i signals are potentially 1080p signals if they are properly de-interlaced. Blu-ray discs and their rivals HD DVD are the only methods to use true 1080p technology on the televisions manufactured today. Blu-ray can perfectly reconstruct a 1080p signal from a 1080i output. This capability, along with the massive storage capacity and quick transfer speeds, makes Blu-ray the forerunner of the next generation of data exchange technology
Also the numerical aperture (NA) of Blu-Ray is wider than that of DVD. These two parameters go a long way in giving Blu-Ray a definite edge in data storage capacity, as well as rate of data transfer and retrieval. blu-ray optical disc format is developed to enable recording, rewriting and playback of high-definition video (HD), whereas DVD optical format can only deliver standard definition video.
