One of the biggest evolutions was the arrival of DVD's. It had a huge impact on the total entertainment experience. Latest blockbuster movies could be watched at the comfort of their homes mainly because with DVD's came the DVD player. High picture quality, audio and video resolution meant that people did not have to waste time at a cinema hall anymore. They could get the same experience in their living room.
After the DVD was engulfed by the world, next came the Blue ray disk with more features. 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 is famously known as a BD or a blue-ray disc. This has been developed by the Blu ray disk association; a group consisting of some of the highly known names in the consumer electronic trade. The most popular names include 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.
Compared to a DVD, the biggest advantage a Blu ray disk has is the high storage capacity. A single-layer Blu ray disk has a storage capacity of 25GB and the dual-layer Blu ray disk can store up to 50GB. It also has advanced audio and video codes, enabling a person can have the ultimate high-definition video viewing experience.
A Blu ray disk, also known as a BD 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, hence enabling it to focus 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. But this 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.
