The Media Factor Of Blu-ray Dvd Disk

The blu-ray is the new, advanced and enhanced disk format in the category of High definition DVD (Digital Versatile Disc). The blu-ray’s media factor is similar to that of the Compact disk and Digital Versatile Disc formats. This new format of blu-ray was introduced and developed by the BDA ( Blu-ray disk Association ). The BDA comprises of many companies related to the fields of Personal Computers and consumer electronics. The blu-ray discs have advantage over other formats of DVD disks, because the recording layer density of blu-ray is about five times more than the other DVD disks.

The blu-ray disks are available both in the forms of single and double layered disks. Work is being done on the four & eight layered blu-ray disks and the maximum recording capacity of these discs will be 200 Giga Bytes. The leading optical storage companies are manufacturing the blu-ray disks and drives. The blu-ray DVD disks and drives can be used in automated system and therefore, the blu-ray technology is useful in archive system. The disk library of blu-ray has capacity between 1 Terabyte to 35 Terabytes. The writing standard of data on the blu-ray is in Universal Disk Format (UDF). The recording standard of bluray supports all the leading operating systems.

The libraries of bluray are compatible with the Digital Versatile Disk & Compact disk both in writing and reading. These libraries of blu-ray format also give support to the offline-media management. The libraries can also be mounted in racks. That is why they are considered as robust and reliable. The bluray library is also supportive to the media management & caching algorithm. The drives of the blu-ray are standardized so that the bluray format could compete with the other DVD disk formats for longer period of time.

Both the single & dual layered bluray disks are supported by bluray drives of the 1st generation. The blu-ray disks are also compatible with the other DVD and Compact Disk technologies. The next generation of blu-ray drives will be compatible with both the 100 & 200 Gigabytes bluray discs along with the other DVD formats. The bluray writable disks usually have sectors and the error correction system is also advanced.

The 1st generation bluray drives have transfer speed of 9 Megabyte per second and the next generation drives will have transfer speed of 18 & 36 MB per second. The blu-ray technology is major addition in the optical storage environment.

The single and the dual layer bluray disks have rewritable and write once format.
The other powerful feature of blu-ray is that its surface has a hard coating. In this way the disk is kept safe from scratches. Advancements are being made to take the recording capacity up to 200 Gigabytes. The blu-ray has more capacity because it has small lazer spot. This lazer spot is about 80 percent smaller than the Digital Versatile Disk (DVD). The 200 GB disk will have additional eight recording layers and each layer will have the capacity of 25 GB.
Work is also being done to speed up the transfer rate to 36 Megabytes per second. This will be a significant addition in the optical media. The blu-ray is very secure & safe storage media and is backed up by the leading vendors of media. The other optical formats require cartridge, but is not required by the blu-ray disk because of the hard-coating. The bluray technology is economical and also provides cost benefits to its users. The surface of bluray discs is conductive and they have resistance to humidity, scratch and extreme temperatures.

What Is Blu-Ray?

Back in 1997, a new home video format was introduced that utilised digital sound and video to provide the sharpest images and clearest sounds to homes across the world. The format was called the Digital Video Disc, or DVD, and it has since unseated VHS as the leading home video format all over the world.

DVD seems to be on its way out, however. Just like the large analog VHS tapes before them, DVDs are on the verge of being made obsolete by a relatively new format: Blu-ray.

Blu-ray players and discs were released in June 2006, although they were beaten to the market by HD-DVDs by a few months. Both formats were created to keep up with recently-released high-definition TVs such as Samsung televisions, which provided pictures and sound that were sharper than what standard DVDs were capable of providing. Although B-ray initially faced competition from HD-DVD, B-ray won the "format war" in 2008 when HD-DVD players and discs were pulled from the market.

Blu-ray gets its name from the blue-violet laser that is used to read the discs. The standard DVD player uses a red laser which has a much longer wavelength than blue/violet light. The shorter wavelength of a B-ray laser allows B-r discs to store almost ten times as much information as a standard DVD. Most single-sided DVDs can hold 4.7 GB (gigabytes) of information, which is about the size of a standard-definition two-hour movie with special features. A single-sided B-r disc, on the other hand, can hold 27 GB of data. This is enough for more than two hours of high-definition video or thirteen hours of standard-definition video. A double-layer Blu-ray disc can hold 54 GB of data, which is good for over 20 hours of standard definition video and 4.5 hours of high-definition video. There are currently plans to develop discs with an even higher capacity than that.

While the first Blu-ray players on the market were relatively expensive, their growing popularity and the fact that they are quickly overtaking DVD players on the market has made them more readily available and affordable. High-definition TVs have also grown in popularity, making B-ray players the ideal choice for those who want to enjoy the best movies with the best possible picture and sound quality. B-ray has even started to replace DVD-ROMs in computers as well as DVD recorders. The most advanced computers on the market now come with B-ray drives. For those who want to record their favourite shows on their high-definition TVs there are even now B-ray recorders such as the Panasonic B-ray Recorder on the market now.

The Technology Trends For 2009

Improved Televisions
Let us start with the television. It has been a steady feature in the homes of many people and yet it is one thing that has probably changed the most throughout the years. Last year, the flat panel televisions that were only four inches deep were the big thing. As the thinnest televisions on market, people flocked to the electronics store so that they could have the very best.

But this year, there are televisions that are making their panels only one inch, and in some cases even less, which means there is a new version of the flat televisions on the market. Many of the big name companies such as JVC, LG, Sharp, Sony, Mitsubishi, Samsung, and Hitachi are all jumping on the bandwagon and creating a television that will truly make history with how deep it is, or rather how deep it isn't.

But why do the televisions have to be so thin? The biggest reason is because the thin television gives the consumers much more flexibility with where they put it. The flat televisions help to improve a home, as it is truly a space saver. With how small the televisions are becoming, how does a person hide their DVD players, the cable box receivers, and the connections to their satellite receivers? The lowboy was something that was rather popular in the 1960s and 1970s but is finally making its comeback in 2009. Even though there are other products on the market, the lowboy is certainly the item that is the trendiest for this year. It is deep enough for the flat panel televisions and it is able to hide all of those connections so that the aesthetics of the wall display are not lost.

Blu-Ray Enters More Homes
When it comes to Blu-ray, many people feel as though it is something of the past. The thing is though, there have never been as many choices and options as there are in 2009. People are trying to get their movies and their normal everyday television viewing into the best picture possible. Even though this could not be done before, there are products out there that can now deliver high definition content to several televisions throughout the house. Instead of just having one television with the best viewing or having to purchase separate HD systems for all of the televisions, you can now get great viewing from all TV's with the help of a video distribution system that is HD-compliant.

The least expensive models on the market come from Sony with a price tag of anywhere between two thousand to two thousand five hundred dollars. These systems are the basics. But what about the homes that about more then two televisions? For that, Sony has developed a system as well. The HomeShare HD system can send HD video to up to four televisions. The cost is about one to two thousand per room.

Netbooks
When it comes to wanting the best of the best, 2009 has something great to offer those who love laptops. The Eee PC 1000HE is certainly the largest of the Eee series to date but there are more benefits to it which over shadows the size with no problem. The high-speed wireless capabilities are incredible and the battery life will last a person all day. This truly means that someone can work all day out in the sun or in the local coffee shop without having to worry about plugging in.

The ten-inch display makes seeing what is on the screen incredibly easy and the keys on the keyboard are ninety two percent of the size that would commonly be found on a laptop. This means that the spacing between each key is similar to what would be found on the common desktop keyboard. All in all, this is the netbook that is the best buy. While it may not be as pretty as another laptop or as compact, the features on it far exceed anything else out there for 2009.

And when you are shopping for the latest technology in netbooks, the thing that will be on your mind is what it can do for your personal and business life, not how pretty it looks.

Can It Get Better Then This?
With all of the various things that have already hit the shelves throughout the world in 2009, one would wonder if it could still possibly get any better then it already is. As far as designers and engineers are concerned, there is always room for improvement. There can always be something a little better, a little faster, and a little smaller. 2009 is truly a year that has brought many surprises and will probably bring even more before it is all said and done.

And what will next year bring? A half-inch thick television? Televisions that think more like computers? No one in the general public really knows for sure. What is known though is that we will most likely be continue to be amazed with what technology brings our way.
