With smaller wavelength, the LASER point is heavily concentrated leaving data to be written with great accuracy and precision. This disc also has a dual layer to hold more contents leaving it to higher specifications.
Coming to its specifications this disc has a capacity of 25 to 50GB for single layer and 50 to 100GB for dual layer. It has a block size of 64KB ECC.The encoded format includes that of MPEG-2, MPEG-4.The standard size being 8cm to 12 cm. 1920Ã—1080 pixel resolution is required in order to write HD videos. The writing speed being 54mb/sec for 12 X drive. A mini BLU-RAY DISC is also available. Cartridges are used to hold these discs to avoid scratches. BLU-RAY is available in BD-R as well as BD-RE.
