Sharp develops laser for 100GB Blu-ray discs

Sharp laser burns 3-, 4-layer Blu-ray

Sharp on Friday revealed a blue-violet laser that it says could lead to triple-layer or even quad-layer Blu-ray discs. The light is as strong as 500mW and achieves the feat by putting an aluminum oxynitride layer between the laser's crystal and the usual dielectric film meant to protect the laser, eking out more output than would normally be possible with just the dielectric element alone. It would not only allow a drive to read twice as deep as current dual-layer Blu-ray drives but would let it write at 8X speed on all four layers.

Using current technology, which fits 25GB for each layer of a disc, the advancement would allow 75GB or 100GB recordable discs and would be useful not just for data backup but also for producing and editing movies, where the size of 1080p movies often limits long-format movies or those with special features.

Sharp hasn't said how soon it would expect the technology to reach shipping products. [via Tech-On]
