普通CD的存储量为680MB,俗称海量存储器。但随着现代科学技术的发展,信息量(尤其是数字视频数据)呈几何数字增长,使人们产生了对更大容量存储器的需要。DVD数字存储技术正是为了满足这种需要而诞生的,并且比DVD密度更高的存储媒体格式也已在开发之中。 随着光盘密度的不断提高,显然现有母盘刻录设备、生产工艺和技术等已经不能满足要求,那么生产高新格式盘
Ordinary CD storage capacity of 680MB, commonly known as mass storage. However, with the development of modern science and technology, the amount of information (especially digital video data) has increased in geometric figures, giving rise to the need for larger memory capacity. DVD digital storage technology was born to meet this need, and storage media formats that are more dense than DVDs are under development. With the increasing density of the disc, it is clear that the existing master recording equipment, production technology and technology can not meet the requirements, then the production of high-tech format disc
