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 various types of optical disk drives in the market but the most recent one’s to have captured the consumer electronic market 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. During the whole disk reading process, a laser beam is projected on the disk. This reflects a light. The light changes according to the different effects of the magneto-optical Kerr.
The BDA, also known as the Blue ray Disk Association consist of some of the well known consumer electronic giants. According to them 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. 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 who released products such as 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.
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 shipped with the Blue ray drives installed in them. The Sony Playstation-3 was one of the first to use the Blue ray technology.
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 would want a DVD with low storage space when a Blue ray disk can be purchased with higher storage space and more features?
