The optical disk technology has by far reached its potential in today’s world. An optical disk is a medium used for data storage and an optical drive is what’s used to read these disks and also to write on them. The Blue ray disk is an optical disk that consists of a ferromagnetic material that is sealed with a plastic coating. There are various types of optical disk drives and some of the famously known one’s are the Blue ray drives. The Blue ray drives enable the reading and writing of data on to a Blue ray disk with storage capacities of 25GB to 50GB. Unlike other disks, the Blue ray disks are readable and writable on both sides.

The way the Blue ray drives work is quite fascinating. The Blue ray drives have a laser inside it. The computer can actually read and write data on to a Blue ray disk because of this laser. When the laser is projected on the Blue ray disk, a light reflects, helping the computer understand the disk format. The light can change depending on the magneto-optical Kerr effect.

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 DVDs and CDs. This is known as backward compatibility. During the early days there were a few manufacturers who released products that had Blue ray DVD players and Blue ray drives which could play only DVDs and not CDs. But today, the new advancements have changed the Blue ray drives making it possible for the 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.

Large data amounts can be archived with the help of Blue ray technology. If you check with the latest models, you will notice that Blue ray drives are being incorporated in almost every laptop and desktop computer. Majority of the computer systems are shipped with the Blue ray drives installed in them. The Sony Playstation-3 was one of the first to use the Blue ray technology.

For manufacturers of traditional DVDs and CDs, the Blue ray disk has come up as a major competitor, enveloping most of its customers. After all who wouldn’t want a disk that has extra storage capacity and works wonders?
