How Is it That Blu Ray Can Store So Much Data?

Blu Ray Disc Player

Now I’m pretty sure everyone has heard of Laser Blu ray and what is its power. However, the few lines that follow are for those of you who do not know what is or is capable of. Blu-Ray was released from the law, if Sony HD-DVD was in its heyday. For now, all films will be published on HD-DVD and have bought most people already, HD-DVD. However, Sony went and announced Blu Ray. They say they’re much more data capacity and transfer rate than any other format is available at the time or always. Blu Ray may have done five to ten times more data than conventional DVD store. However, the only problem is that with this new format, Sony is not compatible with all other stakeholders, including the new HD DVD players have found the time very popular. Blu-Ray can be read on his players. This creates a problem for HD-DVD built-owners, who have already bought HD DVD players and movies that are not exclusive to Blu-ray.

A Blu-ray look like any other DVD, the same size and dimensions. But if this is the case, then you can store the data in question form? The answer lies not in its size but in its read / write technology. Blu-Ray uses a blue-violet laser with a wavelength of 405 nanometers to read and write data to disk. This laser technology is in its name. To use, unlike the first generation of Blu-ray DVD and CD of a red laser with a wavelength much more data to read and write.

Since this wavelength is written more about the data on one disc. The shortest wavelength of the data with greater accuracy leads to more capacity will be written. A single layer disc can store up to 25GB of data, and can be a double-layer support up to 50GB of data. While the other side of the first generation of DVD uses a red laser to write a wavelength of 650 nanometers in the data. Therefore, only then can be saved on a disk of 4.7GB single layer.

With this technology, Blu-ray would be used as a medium of choice for storage. And as technology advances, the price of a Blu Ray also fall. And thanks for personnel Blu-ray technology is available to the film industry, but will be with the owners of a Blu-ray.
