100GB Blu-ray disks that make the current generation look decidedly anaemic will be on the market within about two years if a breakthrough from Sanyo gains acceptance.

The Japanese firm has come up with a more powerful blue laser diode that can burn through BDs far enough to accurately write four 25GB layers per disk.

Current Blu-ray disks top out at two layers and a maximum of 50GB for storing video and data.

Fast too
