The Usages of Blu Ray Disk that You Need to See

The entertainment industry in the latest century has given the world some of the biggest evolutions. Starting from the CD and moving forward with the DVD, entertainment has actually come to its customers door step. Latest blockbuster movies could be watched 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.

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 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. A Blu ray disk is used for 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. 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 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. A Blu ray disk can store around 9 hours of high-definition video and 23 hours of standard-definition video on a 50GB disk. Another advantage of the Blu ray disk is that the blue-violet laser in it 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. Luckily this problem is being rectified by many consumer electronic manufacturers making sure they release 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.
