Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage medium. Its main uses are high-definition video and data storage. The disc has the same physical dimensions as standard DVDs and CDs.



The name Blu-ray Disc is derived from the blue laser (violet-colored) used to read and write to this type of disc. Because of the wavelength (405 nanometres), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A dual-layer Blu-ray Disc can store 50 gigabytes, almost six times the capacity of a dual-layer DVD, or ten and a half times that of a single-layer DVD.What is the best way to store digital data?
