Blu-Ray Innovation In A Nutshell
Author: Michael Zeet
Gone are the days when people had to endure tapes in order to
watch their favorite film. The trouble with VCR tapes is that
they are hard to rewind and fast forward when need be. When you
skip a scene without your intention, it's often hard to go back
to that because tapes run in film rolls even when using VCRs and
not the usual projectors. In addition, tapes are also more
vulnerable to scene deletions. One unauthorized press of the
record button can send an entire film into oblivion.
Then eventually, the advent of CDs as means of distributing
data also came to be. The advent of using discs did not just
prove to be very useful when it comes to distributing film
copies. Even other forms of media such as music albums and data
transfers between computers have found the necessity for using
CDs. But just as people have begun to really appreciate the use
of CDs in our everyday lives, things have been taken further by
the release of Blu-Ray technology.
Blu-ray takes using DVDs up a higher notch. With blu-ray discs,
people can finally manage using high density data and store them
accordingly. The name blu-ray is coined from the blue violet
laser color being emitted for file utilization. Blu-ray discs
use shorter wave lengths with a bluish colored laser. In effect,
this makes the disc effective for storing higher types of
information as compared to usual CDs and even DVDs. The laser
being used and emitted in blu-ray discs is essential because
this is the tool that reads the data. Even CDs and DVDs use
laser technology to facilitate data transfers and recording,
however it uses longer wave lengths which affect the storage
capacity of the disc.
One may ask however, how can a laser beam actually cause much
when it comes to producing greater memory capacity for discs?
Laser technology is generally used by discs, both DVDs and
blu-ray, when it comes to file transactions—recording, playing,
viewing, etc. Lasers are emitted onto the surface of the disc
and the focus of laser beams become embedded onto the disc. The
larger the focus, the larger the spot is brings onto the disc.
The spot will eventually occupy its own space even if does not
contain any relevant information. In effect, it becomes a waste.
With blu-ray technology, smaller laser beam focus is produced
because it has shorter wave lengths. In effect, lesser spots are
produced and bigger memory capacity is left for the disc.
Blu-ray discs are still at its prime. However, it is already
being compared with DVDs from all angles. It is expected that
eventually, blu-ray discs will increase in advantages as it is
already doing so at present. It is now being widely used not
just in film formats but also in gaming devices such as the Sony
Play Station. The technology which blu-ray is made from also
looks promising in itself because the production of laser beams
can also be used eventually for broader purposes.
