摘　　要：信息技术的不断发展,使人们对信息存储密度的要求不断提高。但随着记录密度的提高,单位信息位越来越小,晶粒尺寸也越来越小,磁记录介质的稳定性或抗干扰问题也引起了人们的关注。本文介绍了高密度磁记录介质的稳定性问题及研究进展,特别是利用损伤扩散方法研究高密度磁记录介质稳定性的基本思想、目前取得的主要结果、面临的问题和可能的解决办法。The ongoing development of information technology enables people to increase continually their demands on the density of the information recording. However, with the record of the density increases, the information bit and the grain size become smaller and smaller, and the Stability problem or the ability of the anti-disturbance of the magnetic recording media are also attracting much attention. The stability problem of high-density magnetic recording media and its research progress are introduced, including the basic ideas, the development, the facing problems and possible solutions for using of the method of damage spreading for the stability research of the high-density magnetic recording media.
