Blu-ray Disk
Reviewed by Bram P
The fast evolution of technology made humans experience the latest advancements in the entertainment industry. One of the biggest evolutions was the arrival of DVD’s. It had a huge impact on the total entertainment experience. 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. 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.
A Bluray disk has the same physical attributes as a standard DVD. The Bluray disk has taken the optical disc technology to a higher level as it is mainly used for high-definition data and video storage. The Bluray disk uses a blue-violet laser instead of the red laser which is used in the traditional type of DVD’s and thus named ‘Blu ray’ by every one.
The Bluray disk was developed by the Bluray 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 Bluray disk enables recording, rewriting and the playback of high definition video.
When talking about advantages, one of the major advantages a Bluray disk has over a standard DVD 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. A Blue ray disk has advanced audio and video codes, enabling 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. Another advantage of the Blu ray disk is that the blue-violet laser in it has a shorter wavelength; focus is made on a disc area with greater precision. The size of the disk is the same as a CD, but the storage capacity is much higher.
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.
