Blu-Ray Vs HD DVD

Tags : 

The goal to improve upon DVD technology brought about a surprisingly fierce battle to produce “the product” that would replace DVD technology. This race was run primarily between HD DVD technology which was being developed by Toshiba and Blu-ray technology which was being developed by a conglomerate of contributors known as the Blu-ray Disc Association (BDA).

What is Blu-Ray?
Blu-ray technology was developed by a group of developers and contributing companies so as to improve, and ultimately replace DVD technology. A major feature of Blu-Ray technology is that it uses an optical disc and so is not starkly different in appearance to a DVD. It also uses a blue laser to read the data on the disc. This blue ray allows for greater accuracy in accessing data and therefore allows data to packed much closer and tighter together. This means that Blu-ray discs can potentially hold more data than the original DVD.

What is HD DVD?
HD DVD or High-Definition/Density DVD is a technology that is no longer being developed. Like Blu-ray and DVD, it uses an optical disc which is capable of storing very large amounts of data. HD DVD technology made use of a blue laser as opposed to the red laser used in original DVD technology. Although HD DVD was a promising format, over time, it did not manage to gain popular support. This was true especially among manufacturers and retailers, the place where it needed it most. When the majority of the market chose to work with Blu-ray, the development of HD DVD was discontinued.

Blu-ray technology continues to increase in popularity and it is now positioned to be the technology that ultimately replaces the popular DVD format that we have become used to. Other benefits of Blu-ray technology are that it is backward compatible with DVD and CDs. This is excellent because users will be able to avoid having to re-format or re-record their entire CD and DVD collections. It also means that recording older discs over to the new technology will be much easier than has been with previous replacement technologies.
