"JAPANESE HARDWARE maker Pioneer has developed a technique which will allow optical drives to store 500GB of data.

The paper reported that Pioneer uses the beam to write data holes in a master disk, each separated by 70 nanometres.

That gives a data rate 20 times more than the blue laser Blue-ray disk."
