Blue Ray Drives

It seems like each year there is some new advancement made and the technology keeps improving day by day. Currently the biggest evolution is the Blue ray technology.

But before talking about that, it is better to learn more about the Blue ray disk and Blue ray drives. The Blue ray disk is an optical disk that consists of a ferromagnetic material that is sealed with a plastic coating. There are different kinds of optical disk drives and some of the famously known one’s are the Blue ray drives.

A single-layer Blue ray disk can store around 25GB and a dual-layer disk can store 50GB. This storage space is way higher than a normal DVD. Blue ray drives are needed to read and write data on to a Blue ray disk.

Blue ray drives work in a very different way than other disks that we all know. The Blue ray drives actually have a laser inside that helps the reading and writing of data more understandable for the computer. When the laser is projected on the Blue ray disk, a light reflects, helping the computer understand the disk format. The light changes according to the different effects of the magneto-optical Kerr.

The BDA, also known as the Blue ray Disk Association recommends that almost all Blue ray drives should be capable of reading the traditional type of DVD’s and CD’s. This is known as backward compatibility.

Watching movies can now be done from a Blue ray disk, using a Blue ray DVD player, or a computer or laptop that has Blue ray drives. Blue ray disks come with more storage space and higher quality than a normal DVD, making it more useful for people who want to get a cinematic experience right at their home.

In the early days where the Blue ray technology was at its initial stage, a few manufacturers used to make products that had Blue ray DVD players and Blue ray drives which could play only DVD’s and not CD’s. But today, many companies have rectified this problem by improving the quality of their products. These days you will be able to purchase Blue ray drives and players that can read DVD’s as well as CD’s.

Having a high storage space compared to other disks is one of the biggest advantages the Blue ray disk has. Due to the increase of sales, manufacturers of desktop computers and laptops have incorporated Blue ray drives into them. Many computer systems are now being shipped with the Blue ray drives installed in them. The Sony Playstation-3 also has a Blue ray drive that’s built-in.

Competition between DVD manufacturer’s and Blue ray drives have become very fierce as the Blue ray disk has more plus points than the DVD. After all who wouldn’t want a disk that has extra storage capacity and works wonders?
