There is an ongoing battle between Hd Dvd (High Density Digital Versatile Disc) and Blu Ray Discs. Right now Blu Ray is taking the world by storm primarily using the Playstation 3 game console. It is desperately trying to take over the Dvd market and gain a larger share over Hd Dvd. It is doing a good job of it too. For many people, buying Hd Dvd and Blu Ray products is rather common but the average person still does not know the difference between the two other than one holds more data space than the other. Here is a breakdown and an answer to the question of what is the difference between Hd Dvd and Blu Ray.
What is Hd Dvd? Hd Dvd is the abbreviated version of High Density Digital Versatile Disc. It is a digital optical media format (dvd or disc) that is used for high definition dvd players. It along with the Blu Ray disc uses the same size disc/cd which is 120mm in diameter and a 405 nanometers wavelength blue laser. The old dvd used a red laser which had wavelengths of 650 nanometers. The longer wavelengths are not capable of consistent clarity which limits their ability to focus directly on a surface. The Blu Ray lasers wavelength is shorter causing it to read and write data over a tighter surface which allows for more data storage on a disc the size of a cd. This essentially answers the question from a scientific point of view of what is the difference between Hd Dvd and Blu Ray.
From a consumers point of view and why anyone would be interested in either the Hd Dvd or Blu Ray here are a few facts. Both discs can hold many times more data than the old Dvd. The Hd Dvd can store more than 30 gigabytes of data while the Blu Ray disc can store 50 gigabytes of data. A single sided Hd Dvd can store 15 gigabytes and a dual layer 30 gigabytes. A single sided Blu Ray disc can store 25 gigabytes and the dual layer Blu Ray can store 50 gigabytes. The playback and recording time for the Hd Dvd is 4 hours for 15gb and 8 hour for 30gb. Blu Ray has a playback and recording time of 6 hours for 25gb and 13 hours for 50gb.
There are other reasons that can answer the question of what is the difference between Hd Dvd and Blu Ray. Here is a very powerful difference between the two. It is two letters and a number, PS3. The Playstation 3 is the difference maker between both media outlets. Currently it houses Blu Ray technology that enables it to really take advantage of movie and game storage.

The PS3 is so sophisticated that it allows PS3 owners the privilege to download any media onto their Blu Ray storage area and immediately begin playing games without the need for a disc ever again.
