Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format. It was designed to supersede the DVD format, in that it is capable of storing high-definition (720p and 1080p) and ultra high-definition video resolution (2160p).
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. Blu-ray uses a 405nm blue-violet laser. This shorter wavelength allows the laser to be focused with more precision, which allows more data to be packed in the same space.
