随着硬盘记录密度的不断提高.磁头和盘片之间的间隙降低到只有几纳米,因而磁头的动力学特性对于硬盘整体性能的影响尤为重要.在过去几十年中,以Reynolds方程为基础,学者对磁头运动的物理模型进行了广泛的研究.首先介绍了5种常用的磁头运动模型,并进行了比较分析,对国内外的最新研究状况作了介绍,如模型的求解、磁头受力分析和磁头设计.最后,介绍了目前在空气轴承磁头(air bearing slider)研究中面临的主要问题以及对这些问题的看法.

As the magnetic recording area density increases,the clearance between the slider and disk decreases to several nanometers,so the dynamic characteristic of the slider is quite important to the performance of the hard disk drives.Five models used to describe the dynamic characteristic of the slider are introduced and compared.Then related works,such as models'solution,analysis of forces on the slider and slider designing,are presented.At last,the current main problems and the authors opinions on the problems in the field of air bearing slider are presented.
