TDK Develops a 320GB Blu-ray Disc
Playstation 4 sure to use blu ray!?

TDK is set to demonstrate a 10-layer 320GB Blu-ray Disc at CEATEC in Japan this week.

The company was able to expand the capacity of each layer from the standard 25GB to 32GB, and stack them them up to 10 layers thick while using existing Blu-ray technology.

TDK was able to do this by altering the material of each layer to operate at higher efficiency.

After testing, TDK determined that the error rate met the threshold for wide- spread use, and are currently determining commercial viability for the product.

What has this got to do with games? Well if this can be read by PS3/PS4 we'll see blu ray on the shelves for a very long time.
