This future optical disc format – BRD (Blue Ray DVDs is a remarkable invention of the BDA (Blu Ray Disc Association) that consists of TDK, Thomson, Sharp, Pioneer, Philips, Mitsubishi, Sony, JVC, Panasonic, Samsung, Apple, Hitachi, LG, Dell and HP). The Blu Ray Disc Association has the globe’s most prominent manufacturers of PCs, consumer electronics and media.

DVDs, lets face it have its days counted. The necessity for storing HD content is increasing daily in the light of increasing number of people turning to HD television for their latest digital television fare.

But, DVDs support a resolution up to 720×480 pixels while high definition content resolutions are as high as 1920×1080 pixels. HD video content uses up a considerable amount of hard drive space too. Two hours of HD content with data compression necessitates up to 22 GB of storage space while a DVD-18 disc (dual-sided dual-layer disc) has a storage capacity of only 17GB.

The solution to this problem has let to the development of two technologies – HD DVD and Blu Ray DVDs – that are now in fierce competition with each to gain market share and become the successor of the DVD.

Though these two technologies are apparently similar to each other, the blue ray DVDs have a slight edge over the other as it boats of a greater amount of storage capacity than the HD DVD. As the name denotes, the blue ray discs make use of a blue-violet laser to write and read data in contrast to the existing technology which makes use of red laser. A blue-violet laser (405nm) has a far shorter wavelength than a red laser (650nm) making it feasible to focus the laser spot with superior precision. The advantage of this is that, it permits data to be stored in less space since the data can be packed more tightly, which further, allows consumers to fit additional data on the disc even though it may be the same size as a CD or a DVD.

A single-layer HD-DVD disc only store 15 GB whereas single-layer blue ray DVDs can store 25 GB which is more than 2 hours of high-definition video and 13hours hours of standard video. A dual-layer HD-DVD can hold up to 30 GB whereas dual-layer blue ray DVDs can store 54 GB which is 4.5hours of high-definition video and more than 20hours of a standard video.

Blue ray DVDs are also light on the manufacturers since these are built by injection-molding process on a single 1.1-mm disc compared to the traditional injection-molding process on a 0.6 mm (HD DVD follow the same method) which thereby reduces costs. This savings balances out the expenses of adding the protective layer required on blue ray DVDs which means that the end price cannot be very different from the price of a regular DVD.

Registry issues can really have a huge effect on your PC’s performance. I’d like to discuss with you the best registry fix to get your computer running in peak condition and eliminate many of the problems one may face with a slow computer. I’d like to give you a few ideas on the easiest way to maintain your registry’s health.

The Windows registry located on a PC is typically a large ‘hive’ of information being stored on the hardware components and software that are installed within a system. The registry also contains user preferences and policies which instruct applications to run specifically how the user has configured them.

After periods of regular use, a computer will contain invalid entries within the registry which are caused by programs that do not entirely remove their registry entries during un-installation and removal. Another one of the most frustrating causes of corrupt entries is viruses or spyware which can leave users scrambling for the best registry fix.

There are an overwhelming amount of registry repair programs available on the market and many of them will do little to nothing for fixing registry errors. Some of these applications can even make things worse by removing the wrong entries from the registry and also being very complex, causing nothing more than a headache for users in the end.

The best registry fix is usually finding a software package that has good user feedback, is easy to use, and will perform all the required tasks. Reviews of registry cleaners can be easily located on the internet through search engines, but you need to be cautious of whose advice you take and whom you’re trusting.

I have a short list of programs that I suggest to my readers and clients. These highly rated registry cleaners are proven and offer a TON of great features, but the few that stand out are:

* The ability to backup and restore the registry
* Fine-tune the applications that automatically start up with your PC
* Automatically tweak the system registry for top performance

With so many applications and programs being installed on computers, it’s important to keep the system clean and secure. Registry cleaning applications allow users to quickly and efficiently scan, repair, and backup their registry and get back to doing the things that are important. Nobody wants to waste their time tracking down solutions to registry problems, especially when there are applications available that can do the dirty work for you, am I right?
