一、什么是VMD?正当下一代高清光盘格式——Blu-ray和HD DVD争夺主流媒体霸主之时,另外一股新兴势力已悄然诞生,那就是英国的NME公司(New Medium Enterprise Inc.)推出的通用多层光盘(VMD:Versatile Multilayer Disc)。VMD与现有的蓝光Blu-ray和HD DVD格式不同,它沿用了现有DVD的红色激光技术,只是通过增加记录层的方法来提高存储容量。VMD光盘将现有双层DVD扩充为四层结构,从而实现单层容量5GB、总容量达到20GB,介于单层HD DVD和Blu-ray的存储容量之间。
First, what is VMD? While the next generation of high-definition disc format - Blu-ray and HD DVD for mainstream media overlord, another emerging forces have quietly born, that is, the British NME Corporation (New Medium Enterprise Inc.) introduced Of the Universal Multi-layer Disc (VMD: Versatile Multilayer Disc). Unlike the existing Blu-ray and HD DVD formats, VMD follows the existing DVD’s red laser technology, but increases storage capacity by adding layers of recording. The VMD disc expands the existing dual-layer DVD into a four-layer architecture, delivering 5GB of single-layer capacity with a total capacity of 20GB, between the storage capacity of a single-layer HD DVD and Blu-ray.
