Blu-ray Defined. Blu-ray is a high-definition optical disc format. By using a blue-violet laser, as opposed to the standard red laser to read and record data, Blu-ray allows for the storage of high-definition video and large amounts of data.tandard DVDs are recorded and read using a 650nm red laser.
