A new disc format made by Sony Corporation. It is primarily used to store High Definition video but it can also be used to store data like a DVD. Blu-ray uses a blue laser operating at a wavelength of 405 nm to read and write data. The small wavelength allows to store up to 200GB on a disc in 8 layer mode. A typical single layer blu-ray disc can hold 25GB. A popular video game console that uses blu-ray is Sony PlayStation 3.

What is most likely to become the next form of media. Blu Ray was developed by Sony so it will obviously be on the PS3! Some movies are already using Blu ray technology. Although Blu Ray is Currently not popular (may vary at time period of which you read this) there is still Blu Ray players available (lots of $).

Blu ray disks are basically the thing the will make DVDs obsolete. Like what DVDs did to videos. Each side oh a blu ray disk can hold 25 GB, and dual can hold 50 GB, and get this, they're making a quad-layered one with 100 GB.
Blu Ray + PS3 = lots of $ :(
