Video technology has increased significantly over the past years, and is continuing to grow at an incredible rate. Digital Video Disc’s aka DVD’s are the most likely the last big jump in consumer video technology that everyone is familiar with. To keep up with the ever-advancing world of electronics a new format of video storage has been released called Blu-ray.
Blu-Ray is a next generation optical disc that blows the
socks off of what we all know today: DVD. Conventional DVD’s use a red laser
that have long wave lengths, which limits the storage capacity on a disc.
Blu-Ray uses a blue laser which has much shorter wave lengths. Because the wave
lengths on the Blu-Ray are much smaller it can focus on a spot with much
greater precision, allowing for data to be packed much more tightly than the
red laser DVD’s.
Blu-Ray discs can hold up to 50GB’s of information which 10
times that of a 4.5GB DVD. 10 times the storage greatly increasing the amount
of information that can be saved on any one disc and changes the way we save
information. Dual Layer Blu-Ray discs are able to hold up to 4 hours of
High-Definition Video. High-Definition video is a big hit here, Blu-Ray is an
example of a technology that is making it happen. 50GB is probably comparable
to size of many of old hard-drives, and to picture having all of that
information on a small disc that we can slide into a pocket and take wherever
we want is a bit scary.
Video isn’t the only thing that benefits from Blu-Ray
technology; it is also a standard for PC and other types of storage.
