ray ban But today

The optical disk technology has by far reached its potential in today's world. An optical disk is a medium used for data storage and an optical drive is what's used to read these disks and also to write on them. The Blue ray disk is very much different from a normal DVD and consists of a ferromagnetic material that is sealed with a plastic ray ban eyeglasses coating. There are different kinds of optical disk drives and some of the famously known one's are the Blue ray drives.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 can change depending on the magneto-optical Kerr effect.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 such as Blue ray DVD players and Blue ray drives that played 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.Having a high storage space compared to other disks is one of the biggest advantages the Blue ray disk has. Due to the increase of sales, manufacturers of desktop computers and laptops have incorporated Blue ray drives into them. Majority of the computer systems are shipped with the Blue ray drives installed in them. The Sony Playstation-3 also has a Blue ray drive that's built-in.Competition between DVD manufacturer's and Blue ray drives have become very fierce as the Blue ray disk has more plus points than the DVD. After all who would want a DVD with low storage space when a Blue ray disk can be purchased with higher storage space and more features?

Blue ray discs have revolutionized the digital and multimedia markets in a big way. People are already on the hunt for a good blue ray recorder. Even though the blue ray recorder is only available in Japan yet, it is expected to be released else where very soon.Since the blue ray technology is quite new; many people may lack knowledge about the product. The blue ray technology was first developed by many leading companies involved in the production of digital goods. Sony and pioneer started work on it first, when they were at war with Toshiba’s HD DVD format which was later abandoned. Now the world is eagerly waiting for the world wide spreading of this new high definition blue ray disc and the blue ray recorder. Panasonic is claiming to have come up with a blue ray recorder that can store up to 400 hours of one’s favorite movies. Isn’t that splendid? A blue ray disc has high quality video and audio output giving anyone the ultimate experience in the entertainment field. The blue ray recorder can be seen as a very important tool especially for a teenager having a knack for movies and games, or even a business professional in need of storing large amounts of data.All leading companies such as Sony, Toshiba, and Panasonic are now after the major market share in blue ray recorder software. With a wide array of devices and combo devices which will provide the consumer with more options the blue ray recorder industry is set to be the most competitive market soon. Most companies have gained a head start like Sony and Panasonic. Many more companies has also been up for the challenge.But the biggest problem for these blue ray recorders is that the consumers don’t get many options that come in blue ray discs just yet. So many buyers may think twice before buying a blue ray recorder. But the manufactures have played it well, by producing combo devices rather than sole blue ray recorders. As a result, the consumers are able to watch discs in many formats including the conventional DVD and CD format. What all these means is that until the market is dominated by blue ray discs the consumer is still capable of watching movies in any format. Blue ray recorder devices are expected to dominate the market in the near future. Storing hundreds of movies and watching them with one push of a button may become the norm in the future. So the best thing we can do right now is get ourselves a blue ray recorder and enjoy the show as it unveils. The author of this article has a hobby writing articles in many different topics.

Digital encoded audio & video information is stored on disks in form of pits. These pits are spiral grooves. The pits on the DVD disk have to be more closely packed and smaller in size to store more information. The reading laser has to be more precise in order to read data from the smaller pits. DVD media uses red-laser while blue-laser is used in the new Blu-ray media disc format. This is how the Blu-ray got its name because of the blue laser. As the coming into being of Blu-ray, many famous electronics manufacturers have produced their own Blu-ray players, and as the coming into being of Blu-ray players, many software developers have developed their own Blu-ray rippers for those guys who don’t have a Blu-ray ripper or Blu-ray converter but want to enjoy the high quality of Blu-ray. Red laser has 650 nanometers wavelength. On the other hand the wavelength of blue laser is much shorter which 405 nanometers is. Smaller sized laser beam can focus more accurately and precisely. The blue laser has the ability to read to read data from the pits that have size of 0.15 μm (microns). One micron is equivalent to 10-6 meters. The pits on the DVD disk are twice as bigger than that of the pits on Blu-ray media disc. Track pitch in the DVD disc is 0.74 microns which has been reduced to 0.32 microns in the Blu-ray media disk. The shorter track pitch, smaller laser beam and smaller pits, all these features assist the Blu-ray disk to record data of 25-GB on a single layer. Now the users have more luxury as the recording capacity of Blu-ray media disk is 5 times more than DVD disk. The thickness of DVD and Blu-ray disk is the same. The thickness of both disks is 1.2 millimeters. The data recording procedure is different for both disk types. DVD disc has 2 polycarbonate layers and the thickness of each layer is 0.6 mm. The information which is to be recorded on DVD disk is sandwiched between these 2 layers. A layer on top of the recorded information can lead to birefringence. In birefringence, the laser light is refracted into 2 separate beams by the substrate layer. Data cannot be read from the DVD disk if the laser light splits too wide. Disk tilt is another problem that is caused if the surface of DVD disc is not totally flat or it is not precisely perpendicular to the laser the light. The laser beam distorts due to disk tilt. Very involved manufacturing procedure is required in DVD disk to avoid these problematic issues. These problems have been solved in the Blu-ray disk format. In Blu-ray disk format, the data is recorded on top of polycarbonate layer whose thickness is 1.1 mm. This technique of Blu-ray overcomes birefringence. So as a result the readability problems are avoided in the Blu-ray disk format. In Blu-ray disc format, the objective lens and the recording layer are very closer to each other. This closeness to the objective lens virtually eliminates the disk tilt problem which enhances the performance. The outer side of Blu-ray media disk is protected by a hard coating because the recorded information is very closer to the blu-ray disk’s surface. This hard coating feature makes the Blu-ray media unique, robust, efficient and more advantageous. The hard coating layer protects the Blu-ray disk surface from fingerprints and scratches. Therefore, the Blu-ray media disc is able to store information for longer time periods. Blu-ray media format is more reliable and robust.But you may get puzzled that what to do if I want to enjoy Blu-ray disks on-the-go, for instance, on iPod, should I always bring a Blu-ray player? If you like, you can just choose a Blu-ray ripper, such as a Blu-ray to iPod ripper or Blu-ray to iPhone ripper, then rip and convert your Blu-ray disks to your PC and portable devices. Well, it is all up to you. Hope you can enjoy your Blu-ray life.

A Blu-ray player is a device on which the Blu-ray Disc (BD) runs. BD was developed for the purpose of recording, writing and playback of high definition (HD) video, audio, photos and other digital contents as well as to store huge amounts of data. It is a type of optical disc that has jointly been developed by the Blu-ray Disc Association (BDA) and a group of the world’s leading electronic manufacturers which include Samsung, LG, Sony, Apple, Dell, HP and many others. The Blu-ray Disc has storage capacity of about 27 GB on a single layer disc and a 50GB on the dual layer one. Besides, there are plans to develop a disc with twice that amount of storage.The Blu-ray Disc as opposed to the DVDs (which relies on a red laser to read and write data); uses the blue-violet data and incidentally, derives its name from there too. The benefit of using this laser is that it has a narrower beam which makes it possible to focus with greater precision. Blu Ray allows one to store large amounts of data; indeed, recent development has pushed its capacity upto 500GB! Because of their huge storing capability, the Blu-ray player can easily carry your entire library of songs in a single disc! These discs have upto seven times the resolution of DVDs and therefore can produce the best possible picture quality with sharper details and accurate colour and gives a three dimensional feel even without the 3D technology!To watch blu-ray movies one doesn’t require internet connection. Internet connection is needed for value-added features which include watching recent movie trailers, web browsing, etc.The latest Blu-ray players are also offering connectivity with the internet and are providing support for streaming video on demand. Other applications include the customized internet radio from Pandora and news and weather updates from sources such as the BBC. Though usually these different applications depend on the model of the Blu-ray player, nowadays they are quickly becoming a standard feature.Therefore, if you want to experience a truly unique and beautiful HD visual with the perfect sound, go for the Blu-ray player. But then, before buying keep in Ray Ban 3194 mind and make sure that your TV and the player have matching connections.

The time of conventional DVD had long come to an end. With the ever increasing demand of more capacity and with the movies now being released in high definition format, something new was required to store all this in. Toshiba and NEC came up with a solution; the HD DVD. HD DVD was released way before the Blu-Ray and was being used everywhere in the world but sony as usual had to go and make something completely different than what everyone was using. Sony has a history of doing this like developing the Beta-Max video tape when the whole world was using VHS and Memory Stick flash memory when everyone else was using SD memory cards. Similarly Blu-Ray was developed by Sony and they had to make it completely incompatible with the HD DVD format.All this has accomplished is to make the life of consumers more difficult. Now buyers have to choose between HD DVD or Blu-Ray since both of them are completely incompatible with each other. Furthermore there are titles, in the gaming as well as the movie industry, that are going to be exclusive to either blu-ray or HD DVD.Before I get to my main point of who will eventually win this so called format war, lets first compare the two formats. Blu-Ray is basically the same as any conventional DVD but the data on it is very tightly packed together. They made this possible by using a more precise and accurate laser. They used a blue-violet laser beam instead of the typical red beam used in DVD and CD formats. This allows blu-ray dvds to hold massive amounts of data. Blu-Ray can store 5 to 10 times more data than a conventional DVD. On a single layer Ray Ban 2143 disc they can hold 25GB of data and on a dual layer disc the capacity doubles to 50GB.HD DVD, developed by Toshiba and NEC uses the same data storage technology as the blu-ray. But it is not capable of holding as much data as the blu-ray. The maximum amount of data that HD DVD can store is 30 GB. Though this is much lower than blu-ray's 50GB it is still more than enough for movies in high definition.It can easily be seen that with the way technology is going one thing that we need more of is capacity. Softwares and games that used to come in a single CD or DVD are now being packages as 2 DVD or 3 DVD packs. And with the ever increasing bandwidth available to us people are downloading more and more stuff from the internet. So its clear that the format providing the most capacity will be the one to win the format war. Although the 30GB of HD DVD may seem sufficient now but in a couple of years it will become obsolete just like the DVD.

Once people get a taste of Blu ray films and the features that make the format superior to all others, one of the first questions they ask is, What other movies will be available on Blu ray?.
