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 actually have a laser inside that helps the reading and writing of data more understandable for the computer. During the whole disk reading process, a laser beam is projected on the disk. This reflects a light. 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 DVD’s and CD’s. This is known as backward compatibility.

Although many consumers still use the standard DVD’s and CD’s to watch movies and listen to songs, the Blue ray disk format has gained more popularity over time. This is mainly because of its high storage capacity and outstanding performance. Who would want to purchase a traditional DVD that can store only up to 10GB instead of buying a Blue ray disk which can store between 25GB to 50GB?

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 DVD’s and not CD’s. But today, the new advancements have changed the Blue ray drives making it possible for the backward compatibility.

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 DVD’s and CD’s, 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?
