Quad-layer DVD Technology Becomes the Third HD Format

| Posted: Mar 13, 2007 9:47 pm

whilst HD-DVD and Blu-ray still battle it out for supremacy, a third HD format looks to be on the horizon, with DailyTech having sourced info on a "Quad-layer" DVD disc capable of holding 20GB.

 

This format still uses red-laser technology to read discs, and is stamped as a "Versatile Multilayer Disk" (or VMD) with a maximum of 5GB of data being able to fit on each layer.

 

You can learn more about the upcoming format here peeps.

 


The home entertainment market is still wrestling with having two HD optical formats, HD DVD and Blu-ray Disc, but soon it will have to deal with another. 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.
