【摘要】 信息技术的发展要求存储器件必须具备超高存储密度、超快的存取速率及长的存储寿命。目前所广泛应用的磁存储和光存储介质正在接近其物理极限。故科学家们从多年前就开始积极探索新的存储理论、技术和材料，以期突破数据存储的极限。本文简要地综述了近来该方面的研究进展。更多还原

【Abstract】 Abstract The development of information technique requires that a practical data storage device must possess the character of ultra high density,ultra fast transfer rate and longer longevity. At present, it is reaching the critical point of the most popular magnetic and optical data recoding media. Many research groups have been studing new data storage theory, technique and materials in order to make a breakthrough on the storage density. In this paper, we reviewed the recent development in this field.更多还原
