Sony PDD, Professional Disc for Data, uses blue laser technology to increase the storage capabilities on each disc. Blue lasers have a shorter wavelength than red and can write and read data otherwise overlooked or left empty. Because of this, PDD can hold up to 23 gigabytes on a one-sided disc and greatly reduce the number of discs required for a system or network backup.

These discs are set to challenge CDs, DVDs and backup tapes in the networking community with improved technology and more storage. Minimizing the amount of wasted space on discs has long been a goal of engineers and one that has been partially solved by using blue lasers. There are sure to be additional improvements made but for the time being this may be the best for anyone that is interested in reducing the number of products required to perform a full backup.

Blue Laser Technology

Lasers have long been used in medical procedures as well as for entertainment purposes. You may be familiar with the laser that reads a CD or DVD in your home theater but have not heard about blue lasers which are used in Sony PDD. The laser is able to increase the capacity of a disc up to five times because of its shorter wavelength which creates fewer gaps in transmission.

Sony PDD Flaws

While all the technology sounds terrific and being able to store more data can solve many problems, there are still some issues with these new developments. Because it is still in its infancy stage, the product can be pricey and is generally not affordable to the normal person. And even though it is a newer technology, something more effective may soon be developed.
