Sanyo laser for faster BD
Friday, 17 October 2008
Reports indicate that Sanyo Electric has developed a blue laser diode that will help lay the ground for higher capacity and faster Blu-ray Disc systems. The laser can emit a beam of 450 milliwatts, which is about double the power of Sanyo's current highest power laser for Blu-ray Disc systems. The higher power means it can write and read data on discs with up to four data layers and at speeds of up to 12X, according to Sanyo.
However, while the development of the laser is a step towards such systems, the length of the development cycle and the BD standardisation process means drives and recorders running at the higher speeds are unlikely to be available for another one or two years.
