紧随第1代CD、第2代DVD、第3代蓝光光盘和HDDVD之后,容量高达数百Gb的第4代光盘技术的开发进入了白热化状态。2006年4月底,在加拿大召开的光盘技术国际会议“OpticalDataStorage(ODS)2006”上,行色各异的高密度存储技术展开了激烈的竞争(见图1)。第4代光盘的用途主要被锁定在工
Following the first-generation CD, second-generation DVD, third-generation Blu-ray Disc and HDDVD, the development of the 4th generation optical disc technology with a capacity of hundreds of Gb has entered a white-hot state. At the end of April 2006, intense competition was held in the Optical Data Storage (ODS) 2006 International Conference on Optical Discs held in Canada, with high-density storage technologies of varying colors (see Figure 1). The fourth generation of disc use is mainly locked in the work
