摘要

超大容量的外存储设备在计算机网络日新月异的发展过程中变得越来越重要.而存储容量的增加势必带来由于热衰减现象引起的记录信号衰减的问题.本文通过计算机仿真与实验,研究了磁盘介质中记录信号的热磁衰减现象.文中着重讨论了信号的热磁衰减对记录密度的依赖性,同时考虑了介质参数对衰减量的影响.指出垂直磁记录方式是超高密度记录的最适宜方式之一.

Abstract

Ultrahigh-density hard disk drive is needed with the development of Internet,but thermal decay is becoming more and more significant with the increasing of recording density.In this paper,thermal relaxation in media was examined by simulation and experiments.Bit density dependence of thermal relaxation of recorded signal was mainly discussed and the influence of media parameters was also considered.We pointed out that perpendicular magnetic recording is one of the most appropriate method at ultrahigh recording density.
