Blu-ray – Overview

All of us have come across various disk formats over the years. Blu-ray can essentially be described as an optical disk format of next generation. As data storage requirements seem to have no limits what so ever, blue ray discs will prove to be an excellent solution for the ever creeping demands in the technical area of storage mechanisms. How will it be, if you get five folds more storage than the usual DVDs? Don’t be on your toe, that’s what blue ray offers.

The mechanism incorporated behind the construction of blu ray disc is the primary reason behind the name “blu-ray”. The technologists have adopted a combinational strategy where the blue laser and violet laser operate in tandem for reading/writing purposes. High definition video finds stupendous support in blu ray discs. The formats that are part of blue ray are ROM/R/RW, BD-ROM, BD-R, and BD-RE. Blu-ray with a single layer can accommodate 25GB, whereas one with dual layer accommodates twice the number. It is astonishing to learn that a 50 GB disc can accommodate more than 9 hours long high definition video and the same disc holds standard definition video of about 23 hours.

From the maintenance and protection perspective, blu-ray is definitely the best in its class for meeting objectives. Earlier technologies have adopted cartridges to safe guard the discs. Here, blu-ray goes for a hard coating on its surface to keep itself aloof from scratches, which is the main problem for any DVD. Apart from that, the error detection/correction mechanism in the blu-ray disc challenges others in terms of efficiency and performance. Other main feature of blu- ray disc is that it does not require an internet connection for its primary functioning. For downloading any new features of blu-ray, one will have to go for a net connection.

Blu-ray discs are quite common in European countries these days through some leading manufactures like Sony, Philips etc. Since blu-ray is still in its childhood stage in terms of production amount and sales, the price of it is a wee bit too amicable to the higher side. But, it is expected to come down in the near future, since high definition videos find blu ray as the only best platform to deliver the best along with its fantabulous performance.
