A Short Introduction to Blu Ray

Blu ray is a next generation optical media format developed by the Blu ray disc association, a group of leading consumer electronics and technology companies such as Apple, Mitsubishi, Panasonic, Philips, Samsung, Sony, TDK to name, but a few.

The format was developed for high definition video, as well as storing large amounts of data. A single layer Blu ray disc can hold 25gb of data, which is the equivalent to over 2 hours of high definition television or more than 13 hours of standard definition television. There are also dual layer versions of Blu ray that can hold up to 50Gb of data.

While current optical media uses a red laser to read and write data, the new format uses a blue-violet laser instead. Despite the different type of lasers uses, Blu ray drives can be made backwards compatible.

The benefit of using a blue laser is that blue light has a shorter wavelength so that it can be focused on a smaller target area than a red light laser. This allows data to be packed in more densely allowing more space for data in the same sized physical space.

Blu ray is called Blu ray because it uses a blue light laser to write data onto the disc.

Blu ray is expected to replace VCRs and DVD players and recorders over the coming years because Blu ray offers so much more capacity. Although it will take time for Blu ray technology to be come wide spread because the cost of DVD drives and media is so much cheaper than Blu ray at this time.
