The time has come to let the world know about the Blu-ray Disc (BD).
The Blu-ray or Blu-ray Disc (BD) is now known the next generation optical disc format. The current optical technology of HD DVD uses a red laser to write and read data, while the new format rely on a blue-violet laser, that’s why it was named Blu-ray. One of the benefits of using blue-violet laser is that the wavelength is much shorter than a red laser. This makes it possible for a greater precision. The storage capacity is more than five times the storage capacity of HD DVD. It can hold up 25GB on a single-layer disc and 50 GB on a dual-layer disc. The change to 0.85 of the numerical aperture is what enables Blu-ray Discs to hold up to 50GB.There is an advanced video and audio codecs, that you can offer you a High Definition experience
