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 is a name for a optical disc standard which uses blue-violet laser instead of red laser used in CDs and in DVDs. This allows manufacturers to store more data using the same amount of disc surface. In fact, Blu-ray got its name from the technology, basically the Blu is from blue-violet diode and the ray is from optical ray. The e was intentionally dropped so that the full term Blu-ray could be registered as a new trademark.
