You can hardly follow the optical media storage industry's progress. But you have to. Otherwise you will end up in 20th century while everybody else live in 21nd. This way Sony invented Blu-ray disc format and those BD now taking over DVD and making final shot on CDs head. BD serves the same purposes DVD used to serve - it is storage. Storage that can be used to keep your data and media files. Blu ray disc capable to store up to 25Gb of data (single-layer) or 50Gb of data (dual-layer). But there is more than that here. Blu-ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB-200GB (25GB per layer) in the future simply by adding more layers to the discs. Since BD much like CD before and DVD lately is a media storage the same question arises - every so often you need to rip or grab or whatever word you use the data off the disc for future use on your computer or even for future rewriting on the blank BD writeable media. How do you do it? Of course first of all you will need to get the drive (device) capable of doing it. But more of it - you are going to need special software as well. It can be further complicated by the fact that sometimes these BD discs are copy-protected. Means you cannot do copy of the disc with the most of software rippers out there. Protection is important technology to protect copyright of the authors and treated differently under different laws and in different countries. In some countries it is fully legal to do a backup copy of the product you paid money for, in others it is prohibited. You need to find out what is the case for your own territory yourself. Supposing you found that you do have rights to make a backup copy of the content of your BD but that BD uses some protection mechanism and firmware software which comes with your writer is no good here. What software can be of help? Well it depends on what protection mechanism is used. Most protected Blu-Ray discs use AACS protection which is advanced CSS encryption used in DVDs. What programs can be used to rip AACS protected discs? There are no many these days. I know only of two of them, namely: AnyDVD from SlySoft and http://www.bluraydvddecrypter.com/ - BluRay & DVD Decrypter from Voodoo Media Software. AnyDVD is shareware and BluRay & DVD Decrypter is freeware. I use the latter. Without going deep into technical aspects of grabbing the protected BDs, briefly the success of ripping of some particular disc depends on whether program has special key for this particular media. BluRay & DVD Decrypter has two mechanisms for obtaining these keys. Program connects to the special database of the keys (which gets updated weekly so chances that your BD's key is already there are good) or you can manually enter the key (which can be requested on their community forum). Long story short - Blu-Ray is the technology that comes to replace DVD these days and although writers and discs are still somewhat expensive there're lots of benefits to use the technology already. And software developers are offering products to support legitimate (I hope this is how you are going to use it) use of the technology.
According to the survey findings by the British video association during December, about 1.5m HD Blu-ray disks were sold in Britain. This quantity of sales is almost 400 percent more than previous period in the year 2007. So the grand total for the year 2008 was about 3.7m. Blu-ray system uses latest laser technology that gives better and improved quality of picture and sound as well. The Blu-ray DVD players are capable of playing the DVD discs but on the other hand the DVD players do not have the capability of playing the blu-ray disks. Therefore, the bluray disk player is more advantageous than the traditional Digital versatile Disk (DVD) player.
The blu-ray format is taking over the DVD technology as its sales are increasing rapidly because of its better quality and output. The sales of blu-ray are expected to rise to about 17m as the demand for high definition disks is also increasing. Availability of appropriate storage system and media is significant aspect of High definition. The major manufacturers are focusing on the concentrating and emphasizing of the blu-ray standard.
There was need for developing and enhancing the optical disk technology, so blu-ray disk format was introduced as its next enhanced version. This disk format uses blue-laser whose wavelength is shorter than the DVD format's red laser. The blue laser of the blu-ray format made it possible to store more data volumes in same physical space that the technology of DVD or CD is unable to do so. Blu-ray disc format has become important element of future home portable appliances and entertainment systems. This technology is now considered as universal standard for media streaming applications, hybrid networking and video distribution. Low cost recording material of high resolution and numerical high aperture assisted the blu-ray format to record data of 50GB on dual layered bluray disk.
Low cost trans-coding chips, innovations in drive technology and optics will be needed as the video standards of multiple high definitions emerge globally. According to a survey conducted, over 5 million US homes have installed the 1st generation High definition consumer television displays. Over the next eighteen months, another 9m households are expected to buy the High-definition TV products and within 3 years 30m further customers are likely to purchase them. It is predicted that the households having 16:9 screen HDTV screen is going to increase by 30 percent. This is not going to stimulate the broadcasting of HDTV, rather the consumers want the High definition equipment based cinema as well.
In February 2002, the Blu-ray disk was first introduced that had large capacity and allowed playback, recording and rewriting of data (25GB) on 12mm single sided disk. It uses laser (blue-violet with 405nm of wavelength) for reading the lands and pits. It is due to this shorter wavelength that the blu-ray is able to record more than 120 minutes of HD-video and more than 13 hours of SD pictures on single blu-ray disk. This disc format is backed by PC and consumer electronic companies which include HP, LG, Mitsubishi, Samsung, Sony, Thomson, TDK, Dell, Pioneer, Philips, Sharp and Hitachi. These major companies are promoting the blu-ray disk technology throughout the industries. Its data transfer speed is also very fast (36 MB/sec), therefore it can record HD-video or HD broadcasts from DV camera and also maintain the picture's original quality.
