Sharp manages quad-layer BD
Chris Forrester

Electronics giant Sharp says the company has used a blue-violet laser combination in order to create a 4-layer Blu-ray disc.

The end result is a disc that can handle up to 100GB of storage space.

However, donít expect the device to appear in stores just yet. Standards have still to be established, and only once the industry is agreed will discs and read/write devices appear.
