Why Blu-ray?

In the middle of June 2006, the first blu-ray discs were born, and released on the 2oth of June, 2006. As we know, Blu-ray is the future (or as i see it coming), but the question is why blu-ray? isn't there any one that tried to top the new blue laser technology?

Toshiba, a famous Japanese company, that for sure everybody heard about because of their great reputation in making laptops and other computer-related devices, created a new disk storage technology, the Hd Dvds (High-Definition Digital Versatile Disc). 'HD DVD is derived from the same underlying technologies as DVD. Since all variants except the 3x DVD employed a blue laser with a shorter wavelength, it can store about 3¼ times as much data per layer as its predecessor (maximum capacity: 15 GB per layer instead of 4.7 GB per layer).' http://en.wikipedia.org/wiki/HD_DVD#Disc_structure

So? Which is better? Which 1 are we going to use in the future?

On Tuesday, February 19, 2008, Toshiba announced that it was to drop its format in the HD DVD 'war' with Sony, pioneer and other participated companies. The "High definition optical disc format war". In January, 2008, the main company supporting HD DVD — announced it would no longer develop, manufacture and market HD DVD players and recorders, which holded the blu-ray as victorious.

What you need to know about future storage disks.

The future... How is it?

Many years ago, till today, the progress of new technologies is non-stop. Every single day we hear of a new device that helps make our every day life easier and more entertaining. Televison started from smaller size with less colours to large, hi tech. colourful, plasma slim screens. Computers started from 'Huge calculators!' to small portable laptops with extremely high speed and great storage. Did anyone imagine, during the days of 500 Mbs. Hard disks, that we would reach to be able to store in 10's and 100's of GEGABYTES?! Ofcourse not. I still remember those days when i used fill my floppy with many, many games! Then came the Cds (Compacts Disks). Then cds where developed into Dvds (Digital Video Disc).
These are all OLD news...


What is new then?!

Media is developing as well with technology in many ways, and everyday, the search of better ways to send messages (through media - Like movies, music, t.v... etc). As we all know, Dvds are essential for media, because Dvds are the newest and main technolgy to ditribute video and music files. Well true but not for long. Some of u (especially those of you that have a certain passion in knowing about the newest news of technologies) must have heard about the newest disk storage device or technology (most of you might not), the Blu-ray.
