Starting from the CD and moving forward with the DVD, entertainment has actually come to its customers door step. People did not have to go to the cinema hall to watch the movie they liked. They could experience it all at the comfort of their homes mainly because with DVD’s came the DVD player. These high-tech equipments had unmatched picture quality with high audio and video resolution.

A Blu ray disk has the same physical attributes as a standard DVD. The Blu ray disk has taken the optical disc technology to a higher level as it is mainly used for high-definition data and video storage. Another dissimilarity between a DVD and a Blu ray disk is that a DVD uses a red laser, whereas the Blu ray disk uses a blue laser. The name ‘Blu ray’ was a result of the laser color that was used in the disk.

The Blu ray disk was developed by the Blu ray disk association; a group consisting of some of the highly known names in the consumer electronic trade. Some of them include renowned names such as Sony, Hitachi, Philips, Samsung, Panasonic, Hewlett Packard (HP), etc. The format in a Blu ray disk enables recording, rewriting and the playback of high definition video.

When talking about advantages, one of the major advantages a Blu ray disk has over a standard DVD is the high storage capacity. The storage capacity of a single layer Blu disk is 25GB and the dual-layer Blu ray disk can do up to 50GB. It also has advanced audio and video codes, therefore a person to have the ultimate high-definition video viewing experience.

Unlike the traditional DVD, a Blu ray disk has storage capacity around five times higher than a traditional DVD. These disks can store high-definition video as well as standard-definition video. The standard can store around 9 hours whereas the high-definition video can store up to 23 hours.

Since the blue-violet laser in the Blu ray disk has a shorter wavelength, focus is made on a disc area with greater precision. Although the looks of a CD and a Blu ray disk may seem the same, the storage capacities differ a lot.

The major disadvantage is that sometimes standard DVD players are unable to recognize the format in these disks. Luckily this problem is being rectified by the use of backward compatible players. Many of the CD’s and DVD’s can be used in a player which is compatible with Blu ray disks and DVD’s.
