The Benefits Of Blu Ray Disk
Posted by Goldy in Uncategorized on December 7th, 2010
The entertainment industry in the latest century has given the world some of the biggest evolutions. One of the biggest evolutions was the arrival of DVD’s. It had a huge impact on the total entertainment experience. People did not have to go to the cinema hall to watch the movie they liked. They could experience it all at the comfort of their homes mainly because with DVD’s came the DVD player. These high-tech equipments had unmatched picture quality with high audio and video resolution.
After the DVD was engulfed by the world, next came the Blue ray disk with more features. Unlike the DVD, the Blu ray disk is mainly used for high-definition data and video storage. The Blu ray disk uses a blue-violet laser instead of the red laser which is used in the traditional type of DVD’s and thus named ‘Blu ray’ by everyone.
The Blu ray disk is famously known as a BD or a blue-ray disc. This has been developed by the Blu ray disk association; a group consisting of some of the highly known names in the consumer electronic trade. Some of them include renowned names such as Sony, Hitachi, Philips, Samsung, Panasonic, Hewlett Packard (HP), etc. A Blu ray disk is used for recording, rewriting and the playback of high definition video.
When talking about advantages, one of the major advantages a Blu ray disk has over a standard DVD is the high storage capacity. The storage capacity of a single layer Blu disk is 25GB and the dual-layer Blu ray disk can do up to 50GB. It also has advanced audio and video codes, enabling a person to have the ultimate high-definition video viewing experience.
You can examine the Blu ray disk waveform with spectrum analyzer. This spectrum analyzer is one instrument that is often used for the conversion of higher frequencies. You can find a variety of spectrum analyzers in the market such as spectral analyzer. With these tools, you can check the amazing features offered by the Blu ray disk.
Unlike the traditional DVD, a Blu ray disk has storage capacity around five times higher than the normal one. A Blu ray disk can store around 9 hours of high-definition video and 23 hours of standard-definition video on a 50GB disk. Since the blue-violet laser in the Blu ray disk has a shorter wavelength, hence enabling it to focus on a disc area with greater precision. The size of the disk is the same as a CD, but the storage capacity is much higher.
The major disadvantage is that sometimes standard DVD players are unable to recognize the format in these disks. But this is being rectified by the use of backward compatible players. Such players have the ability of reading Blu ray disks, CD’s as well as DVD’s.
Ensuring The Advantages Before Purchasing Bluray DVD Player

Bluray discs are the newest and the latest when it comes to optical disc storage. Gone are the days when we had to use DVD’s of CD’s for every kind of storage that we could think of. Compared to the 50GB of data that a bluray disc can store, the storage capacity of the DVD and CD which used to seem huge compared to the floppy disk, is actually tiny.
A good bluray dvd player needs to play not only bluray discs but CDs and DVDs as well. As bluray discs are read and written using a different wavelength of rays, the technology used in the bluray dvd player is one that has to be compatible with the new bluray technology as well as the older HD DVD technology.
The bluray dvd player has become a must-have for many now, and there are many models available for purchase at stores and even online. Prices for bluray dvd players can be a little bit more than what you would dish out for a standard DVD player, but then there is the benefit that when you watch movies on the bluray dvd player, you will be able to enjoy better quality sound and video than experienced ever before.
Standard quality is no longer enough, with everyone rushing to get super-high quality goods. We all want to know we are getting the best value for our money. Buying a bluray dvd play ensures that you have the benefit of many new features and get a better viewing experience as well. For example with bluray technology, bluray discs will be capable of holding much more information than before, and so hence a movie could be watched with the added specials in it.
The Bluray dvd player has been released by many companies, all trying to get into the market with the newest technology. Brands like Panasonic, Sony, Philips, LG and Samsung are just some of the brands that have put into the market new DVD players that are compatible not just with bluray discs but with conventional CD’s and DVD’s as well.
This backward compatibility is something completely optional, as when the bluray dvd player is being made it is up to the company to decide if to use a BD/DVD/CD compatible optical head or not, but because of the growing popularity of bluray discs, it would be against the best interests of the company to not include this new technology in their products.

Some Causes Why You Need To Take Blue Ray DVDs
Posted by Goldy in Uncategorized on December 31st, 2009
This next generation optical disc format – Blue Ray DVDs - is a proud development of the Blu Ray Disc Association (BDA) that include HP, Dell, LG, Hitachi, Apple, Samsung, Panasonic, JVC, Sony, Mitsubishi, Philips, Pioneer, Sharp, Thomson, and TDK. The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers.
The days of DVDs are numbered. With more and more people upgrading to HDTV to enjoy modern digital television, the need to store high-definition content is also on the rise. However, DVDs are known to support a resolution of 720 x 480 whereas HD content resolutions reach as higher as 1920 x 1080. High definition video content also consumes a lot of hard drive space. Two hours of HD content with data compression necessitates up to 22 GB of storage space while a DVD-18 disc (dual-sided dual-layer disc) has a storage capacity of only 17GB.
The solution to this problem has let to the development of two technologies – HD DVD and Blue Ray DVDs - that are now in fierce competition with each to gain market share and become the successor of the DVD. Both these technologies are very similar in nature but the blue ray DVDs have an advantage since these boast a far higher storage capacity than the HD DVD.
The blue ray discs, as the name suggests, uses a blue-violet laser to read and write data unlike the current technology which uses red laser. A blue-violet laser (405nm) carries a much lesser wavelength than a red laser. The plus point in this is that as the data could be packed compactly it uses less space to store data and that fact lets users to add more data on the disc though the size of the disc is more or less the same as a CD/DVD.
A single-layer high definition DVD can hold only fifteen GB of data whilst single-layer blue ray DVDs can hold twenty-five GB which amounts to over two hours of HD video and thirteen hours of normal video. A double-layer High Definition-DVD can store up to thirty GB whilst double-layer blue ray DVDs can hold fifty-four GB which is 4.5 hours of HD video and more than 20 hours of normal video.
Blue ray DVDs are also light on the manufacturers since these are built by injection-molding process on a single 1.1-mm disc compared to the traditional injection-molding process on a 0.6 mm (HD DVD follow the same method) which thereby reduces costs. This savings balances out the expenses of adding the protective layer required on blue ray DVDs which means that the end price cannot be very different from the price of a regular DVD.

The Advance Applied Science of Blu Ray Disc
Posted by Goldy in Uncategorized on December 3rd, 2009
The digital world, no matter how advanced it is, is still faced with a few problems and inefficiencies in the products that are being offered. These are quite visible when trying to transport huge amounts of data from one place to another. The standard DVD which was seen as a high quality product is now seen as something not worth watching by many movie lovers.
With the introduction of the blu ray disc, studies confirm a major loss of sales for the standard DVD market. Although the blue ray disc looks a lot similar to the traditional DVD, it has more features and capabilities than the latter. Unlike the DVD which was read by a red laser, the blu ray disc is read by a blue laser projected on the disc and hence the name ‘blu ray disc’ was given.
Then what’s so special about a disc that needs a blue laser? You may ask. Well there are many advanced qualities in the blu ray disc. One of them is the enormous storage capacity. A normal DVD would carry about 5 GB storage capacities. While a blu ray disc can go up to about ten times of that. A dual layer blu ray disc will carry about 50 GB while a single layer blu ray disc will carry close to 25 GB in storage space.
Well if you only use DVDs for movies, games and music you might find that information a bit useless. Even though the increased storage capabilities means the ability to store about 10 movies, as many games or hundreds of audio tracks in a single blu ray disc. How impressive is that.
But all you movie lovers will have better news. The increased high definition effects for both audio and video in the blu ray disc will provide the viewer or listener with an experience of something out of this world. Home theatre has never been better than this. Movie theatres might have to be a bit careful. Also, all gamers out there would find the same special qualities when playing a game on your Play station, Xbox or Nintendo using blu ray disc. Advanced special features and high definition.
Consumer producers of blu ray discs would also find a lot of advanced features that will suit the business needs like advanced security and anti piracy features. Regional codes will also mean that market segmentation and specialization would be much easier than before. The blu ray technology has spread around the globe with positive feedback and a direct hit to the standard DVD market. Consumers who were previously happy with the use of DVD’s to watch movies are now opting for blu ray discs. After all why shouldn’t they? A blu ray disc can give you much more features than a DVD.
