Technology at birth or develop? This fascinating
History, in some great battles, one for good measure,
this is a story worth reading, even if you are not a technology
Addict.
To really understand, Blu-Ray, you should return
In the early 80's, when the CD-ROM or CD-ROMs.
CDs were a big step forward compared to the current
The media at the time, mostly because the CD offers more space,
better sound quality and quickly became a universal standard
Pre-recorded, recordable and rewritable. CD-ROM with more than
650 MB of RAM, a revolutionary at the time
to store and retrieve information.
However, this method is not yet complete, especially taking into account
Our insatiable need for more compact storage and high quality
Pictures. Thus, we had the introduction of DVD in the 90
5-10 X the ability to increase the CD-ROM. At DVD enables
High quality, standard definition video recording and distribution,
not to mention the record more data. Another important
Elements of this smooth transition is that the DVD uses the spectrum
same factors, such as CD, full backwards compatibility.
These factors are not lost in the development of the following
Generations of the media, Blu-Ray discs.
Beginning in the Blu-Ray, starting from the middle of aƱos'90 'S with
introduction of high-definition games. Consumers are more likely to realize its
was unable to media for recording or playback of high definition
Content. This does not mean that could be used for HD with codecs
except JVCs Digital VCR and Sony HDCAM, but nothing
Practices such as CD and DVD.
It is, however, that the use of lasers with a wavelength shorter than
Can high-density optical storage.
With this knowledge, Shuji Nakamura invented practical blue laser
Diodes. Commercial use is protected in the patent application, but
If Blu-Ray and in the next step
in the development of the media started.
The difference: the advantages of Blu-Ray DVD compare.
Even if Blu-Ray disc of the same physical size on a DVD or CD,
have the opportunity to read and more data. Reason
is to use the blue laser instead of red laser --
DVD-ROMs and CDs. The blue laser has a shorter wavelength,
a smaller aperture lens and a thin layer on the disc
makes less than the width of the capacity on the ground
read and store more data on the disk.
Of course, the debate would not be complete without mention of
heated battle between the two technologies: Blu-Ray
HD-DVD disc format against each resources are important for the Blu-Ray
Sony, Dell, Hitachi, Hewlett Packard, Panasonic, Pioneer,
Philips, Samsung ... HD-DVD, and we support Toshiba, NEC and
Some of the largest film studio Universal Studios, Paramount Pictures,
Warner Bros and New Line Cinema.
While many believe that Blu-Ray won the battle, and probably
high-definition technology. (Beta-Who?)
The main argument in the space, as it offers Blu-Ray 25GB
single layer and 50GB dual-layer, as compared to
HD-DVD offers 15GB in single layer and 30 GB dual layer.
This Blu-Ray strongest card, but with a single layer --
Blu-Ray disc can contain 25 GB of data. Compared with
4.5 GB on a standard DVD. As already mentioned, the double
Layer Blu-Ray disc can contain 50 GB. This amount of storage
allows disk images high-definition 1080p.
It has a resolution of 1920 to 1080 pixels progressive scan.
The standard DVD is 720 x 480 pixels. Another advantage of
Blu-Ray is that the bandwidth is much higher than DVD.
It can display signals at speeds of up to 48 Mbit / s is 6
times faster than DVD 8 Mbit / s
In addition, remember the old DVD is not obsolete

Transformations.
Taking all these points and characteristics, the future of Blu-Ray
In fact, looks very bright. Blu-Ray discs and players
