Blu ray disc, also known as BD is similar to CD and DVD which are optical disc storage media formats. On all three of these formats, a laser is used to read and write information on the disc. These discs are the same size as a CD and DVD, but it can hold as much as 10 times the information of a DVD. The reason is due to the type of laser used in the process. DVD players utilize a red laser to read and or write information while blu ray players use blue lasers. The blue laser can be focused to a much narrower point than the red, therefore much more information on the disc can be recorded since it can be placed closer together.
