Kindly explain how a magnetic disk is written or burnt with blue ray

Oct 17th, 2017

The technology employed in the production of Blu-ray Disc is quite distinct and unique. An optical pick-up technique is used in transmitting video, audio, or information unto the BD layer. The Blu-ray Disc (BD) system uses blue light and a high numerical aperture (NA) of 0.85. A cover layer thickness of 0.1 mm is chosen to secure sufficient disk tilt margin [Maxim, 2007].

The next part is the recording layer where the information is written, stored and read. The recording layer works no differently to a DVD. A single layered disc will be burnt with a laser that burns at 4 to 11 mW. Burning the recording layer creates a pit were the information is held; the laser burns the layer at 220oC [webelements, 2005]. BD layer is made of a mixture of four different elements. These are Silver (Ag), Indium (In), Antimony (Sb) and Tellurium (Te).
