In the present day, blu ray discs have made still another upheaval.  This new optical disc format 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.

Blu ray discs provide enhanced storing capabilities, i.e. twenty-five GB on single-layer and fifty GB on dual layer discs. It is the perfect definition of the ultimate user experience and allows the recording, rewriting, playback and distribution of high-definition videos.  The fact that the blu ray discs are based on the bare disc physical form factor renders it compatible with compact discs and DVDs.

Just as its name denotes, blu ray discs utilizes a blue-violet laser beam to read and write data instead of the red laser beam which is being used as per the available technology at present. A blue-violet laser (405nm) has a far shorter wavelength than a red laser (650nm) making it possible to focus the laser spot with superior precision.  The advantage of this is that, it permits data to be stored in less space since the data can be packed more tightly, which further, allows consumers to fit additional data on the disc even though it may be the same size as a CD or a DVD.

Several of the world’s prominent PC and video game makers, recording media and consumer electronics and music companies have taken up this technology today and Hollywood studios and various smaller studios have already taken interest in these latest blu ray discs with the results of some of them already announcing the release of their new flicks on blu ray discs.

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. HD video content uses up a considerable amount of hard drive space too.  High definition content with data compression of about 2 hours duration requires up to twenty-two GB of storage space whereas a DVD-18 disc (dual-sided double-layer) allows a storing capability of seventeen GB only.

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.  Though these two technologies are apparently similar to each other, the blue ray DVDs have a slight edge over the other as it boats of a greater amount of storage capacity than the HD DVD. As the name denotes, the blue ray discs make use of a blue-violet laser to write and read data in contrast to the existing technology which makes use of 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.

Today, the blu ray discs are yet another revolution in technology. This novel optical disc system is an important creation of the Blu Ray Disc Association (BDA) which includes Dell, Hp, Hitachi, LG, Samsung, Apple, JVC, Panasonic, Mitsubishi, Sony, Pioneer, Philips, Thomson, Sharp and TDK. (The BDA boasts 180 of the world’s leading consumer electronics, media and personal computer manufacturers| Blu Ray Disc Association consists of the Globe’s frontline producers of media, personal computers and consumer electronics items, numbering one hundred and eighty}.

The blu ray discs, as the name suggests, uses a blue-violet laser to read and write data unlike the current technology which uses red laser. The wavelength of a blue-violet laser (405nm) is way shorter than that of a red laser (650nm) and this has made it easier to concentrate the laser spot with superb accuracy. The advantage of this is that, it permits data to be stored in less space since the data can be packed more tightly, which further, allows consumers to fit additional data on the disc even though it may be the same size as a CD or a DVD.

They’ve announced it back in June and executed the plan today: Toshiba is now officially a Blu-ray supporter. The company issued a short press release (in English) today, stating Toshiba has applied for membership of the Blu-ray Disc Association (BDA). The BDA is a voluntary membership group aimed at fostering the development of the Blu-ray format on a global scale.

Toshiba took a long time for this decision, as the company buried their own HD format, HD-DVD, as early as February 2008. It also said customers can expect the first Blu-ray players and Toshiba laptops with built-in Blu-ray drives within this year. As to be expected, the word HD-DVD isn’t mentioned in the press release even once.

It’s a good move from Toshiba to finally overcome their pride: In Japan, at least, Blu-ray products are enjoying brisk sales. Blu-ray recorder sales, for example, have been topping DVD recorder sales since November 2008.

In the past, High Definition DVDs and Blu Ray Discs were competing intensely about which would succeed the DVD.  With the results of blu ray discs being the winner, the attention has now been turned on the blu ray drives that will operate the blu ray discs.  As the name signifies, the blu ray technology makes use of blue-violet laser to access data whereas the available technology at present uses a red laser.  A blue-violet laser (405nm) which is very short in wavelength than a red laser(650nm)concentrates the laser spot with superb accuracy.  The plus point of this is that it allows data to be recorded in less space as the data can be stored compactly which gives the users to squeeze in more data on the disc though the size of the disc is akin to that of a CD/DVD. A single-layer HD-DVD disc only store 15 GB whereas single-layer blue ray DVDs can store 25 GB which is more than 2 hours of high-definition video and 13hours hours of standard video.A dual-layer HD-DVD can hold up to 30 GB whereas dual-layer blue ray DVDs can store 54 GB which is 4.5hours of high-definition video and more than 20hours of a standard video.

Anyhow, blu ray drives are undoubtedly dearer than other standard drives.  Blu ray drives that can both read blu ray discs and burn DVDs are about 3 times the price of a standard DVD burner.  And, if you want blu ray drives that will burn the blu ray media, the price increases ten times more.

There are many online shopping avenues for selecting you blu ray drives.  A little research will enable you to find good bargain for your money. Several of the producers of blu ray drives are Sony, Samsung, Pioneer, Philips, Panasonic, LG, HP, and BenQ.  Although it is not compulsory, the BDA blu ray drive manufacturing to allow backward compatibility -reading standard DVDs and CDs in addition to blu ray discs.

Blue ray discs are the perfect definition of the ultimate user experience.  It further allows the recording, rewriting, playback and distribution of high-definition videos. The blue ray discs have been founded on the bare disc physical form factor which makes it compatible with CDs and DVDs.

Blue ray discs 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 which thereby reduces costs. The costs thus saved are spent on the addition of the shielding layer necessary on blue ray discs with the result that the end price being more or less the same as that of a DVD.  Blue ray discs also have a higher data transfer rate of 36Mbps than the DVD’s of today that transfer data at the speed of 10Mbps.  The meaning of this is that it takes just an hour and half to burn twenty-five GB of data onto a blue ray disc.

The conventional DVDs and CDs initially came into the market with merely read-only formats.  The blue ray discs however, plan to provide a wide range of formats that include BD-ROM (read only), BD-R (recordable) and BD-RE (rewritable).

The Blue ray drives enable the reading and writing of data on to a Blue ray disk with storage capacities of 25GB to 50GB. Unlike other disks, the Blue ray disks are readable and writable on both sides.

The way the Blue ray drives work is quite fascinating. The Blue ray drives have a laser inside it. The computer can actually read and write data on to a Blue ray disk because of this laser. During the whole disk reading process, a laser beam is projected on the disk. This reflects a light. The light changes according to the different effects of the magneto-optical Kerr.

The BDA, also known as the Blue ray Disk Association consist of some of the well known consumer electronic giants. According to them almost all Blue ray drives should be capable of reading the traditional type of DVD’s and CD’s. This is known as backward compatibility.

Although many consumers still use the standard DVD’s and CD’s to watch movies and listen to songs, the Blue ray disk format has gained more popularity over time. This is mainly because of its high storage capacity and outstanding performance. Who would want to purchase a traditional DVD that can store only up to 10GB instead of buying a Blue ray disk which can store between 25GB to 50GB?

During the early days there were a few manufacturers who released products that had Blue ray DVD players and Blue ray drives which could play only DVD’s and not CD’s. But today, many companies have rectified this problem by improving the quality of their products. These days you will be able to purchase Blue ray drives and players that can read DVD’s as well as CD’s.

Large data amounts can be archived with the help of Blue ray technology. If you check with the latest models, you will notice that Blue ray drives are being incorporated in almost every laptop and desktop computer. Many computer systems are now being shipped with the Blue ray drives installed in them. The Sony Playstation-3 was one of the first to use the Blue ray technology.

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.  But, DVDs support a resolution up to 720×480 pixels while high definition content resolutions are as high as 1920×1080 pixels. 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 answer to this issue has helped invent two brand-new technologies, namely High Definition DVD and Blue Ray DVDs, which are now locked in an intense battle to clinch market shares and become the successor to 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. As the name denotes, the blue ray discs make use of a blue-violet laser to write and read data in contrast to the existing technology which makes use of red laser.  A blue-violet laser (405nm) has a far shorter wavelength than a red laser (650nm) making it feasible to focus the laser spot with superior precision.  The advantage of this is that, it permits data to be stored in less space since the data can be packed more tightly, which further, allows consumers to fit additional data on the disc even though it may be the same size as a CD or a DVD.
