The Blu-ray disc, which is a high-density optical disc, was invented as a way to store the large amounts of data that HD video creates. Problem solved, right? Well, pretty much, but Blu-ray didn't just happen overnight. Blu ray technology had a long history to become as widely accepted as it is today, and it's just getting started.

In this article, I am going to cover Blu-ray technology history, including its invention, launch, and epic battle with the HD DVD format.

Thus if a double layer is used, they can easily hold information up to 5o GB. The Blu-Ray disc does not have these issues because the data is stored on top of a poly-carbonate layer which is about 1 millimeter thick.

This stops the problem of birefringence and causes no distortion to the reading of data.
