Meet quad-layer DVD, the third high-def DVD format after Blu-Ray and HD-DVD:
UK-based New Medium Enterprises (NME) has developed the Versatile Multilayer Disc (VMD), a new optical-based format capable of storing 20GB of data.
Unlike HD DVD and Blu-ray Disc, VMD is a red-laser technology that achieves its storage capacity by using a greater number of layers. VMD is precisely the same size and thickness as DVD. However, while DVD technology utilizes two layers of a disc, VMD technology has conceived multi-layering, where up to 5GB can easily be stored on each layer.
Naturally, new DVD players will be required. Had enough? I think I’m going to sit this format war out. I’ll just BT anything I can’t find on old DVD. The concept of fixed physical media is so 20th century oldskool anyway.
