.: HD-DVD
High-density Digital Versatile Disc

HD-DVD stands for High Density Digital Versatile Disc and it is one of the newest things that technology has to offer. This disc, original called the Advanced Optical Disc, is the leading competitor of Sony’s new Blu-ray disc.

Both the Blu-ray and HD-DVD offer more space on the discs, between 15-30 GB depending on whether you are using a single or double sided disc. They also offer a nearly identical video format and their method of playing are close as well.

The main differences when comparing the HD-DVD discs to the Blu-ray discs is that it will cost less to manufacture the HD-DVD discs, which will likely mean a lower price for consumers. Compatibility issues with other forms of media are more likely when using a HD-DVD drive as opposed to a Blu-ray. One last difference is that Blu-ray includes what is called a DVD backward compatibility.

The HD-DVD discs are used and played much like any other disc of this kind. One of the main differences is the lasers. Instead of the more traditional red lasers that are used in common CD and DVD disc drives, these lasers are blue.

HD-DVD drives and discs were approved by the DVD Forum in 2002. Since then they have been working hard to produce them in hopes that there would be numerous models on the shelves in 2005.

One of the things that will make HD-DVD drives convenient is that you will still be able to play other forms of media in them. Most DVD media forms will be playable in the drives. This means if you plan to replace an existing DVD drive with the new HD-DVD drives then you won’t have any problem doing so and all your previously stored media will work like a charm.

As the HD-DVD discs and drives are set to take over HDTV you can soon expect to see them everywhere. Prices and features will vary but the quality and compatibility issues make the product worth considering if not buying.
