Which storage technology does a Blu Ray disk use?

A Blu-ray disk is an optical storage device similar to CD and DVD technology. It also uses a laser to read and write to the disk, but instead of a red laser beam, as used in DVD and CD, it uses a blue-violet laser beam. This means it can burn smaller pits on the disk and so it has even more storage capacity than a DVD.
