超高密度、高速光磁混合数字信息存储技术和存在的问题

RESEARCH AND PROBLEMS IN THE ULTRA HIGH-DENSITY OPTICAL-MAGNET MIXED DIGITAL STORAGE

随着现代社会和科学技术的高速发展,信息量急剧增加,对信息的处理、传输以及存储容量的要求越来越高,研制开发具有超高密度、高速数字信息存储技术及盘片不仅具有重要的科学意义,而且有着重大的经济价值。本文是在国家自然科学基金委员会信息科学部组织的“超高密度、高速信息存储技术的研究”研讨会的基础上,对当前国内外光存储、磁存储和磁光存储的研究背景及发展现状、存在的问题进行了分析,并对科学基金今后支持的几个研究方向作了介绍。

With the development of modern society and scientific technology, the demand of information storage with large capacity, high density, high data process transfer rate and low production cost has been increasing dramatically. Therefore, it has been of great scientific and economic signification to research and develop the storage technique of ultra high-density, faster data transfer rate. In this paper, the current research status and existing problems in the optical storage , magnetic storage and magneto-optical storage are analyzed in the world, and some research targets supported by NS-FC are introduced.
