Versatile Multilayer Disc (VMD or HD VMD) was a high-capacity red-laser optical disc technology designed by New Medium Enterprises, Inc. VMD was intended to compete with the blue-laser Blu-ray Disc and HD DVD formats and had an initial capacity of up to 30 GB per side. At a physical level, VMD is identical to DVD, but with the possibility of using more layers.
