What is Blu-ray?

Blu-ray is a digital optical disc storage format designed to supersede the standard DVD format. The name "Blu-ray" refers to the blue laser used to read and write data on the disc, which allows for greater storage capacity and improved quality.

Standard DVDs use a red laser with a wavelength of 650 nanometers, while Blu-ray discs utilize a blue-violet laser with a wavelength of 405 nanometers. This shorter wavelength enables Blu-ray to store more data in the same physical disc size, allowing for high-definition video and audio content.
