| 摘 要： | 高密度硬盘介质静态磁性参数的精确测量对研制高密度硬盘至关重要.本文从测量系统和材料两方面对玻璃基噪声的影响机理做了较详尽的分析;并介绍了消除玻璃基噪声影响的四种方法,这四种方法在测量同一硬盘介质静态磁性参数时相对偏差小于5%,因此这四种方法都是切实可行的.

| Abstract: | Accurate measurement of static magnetic parameter of high-density hard-disk media is vital for research and development of high-density hard-disk. This paper analyses the influence of glass substrate noise from measuring system and media at large. Four methods of eliminating glass substrate noise are introduced. Comparative error among these methods is less than 5% for same media of hard-disk. So the four methods are executable. |

| Keywords: | high-density hard disk glass substrate static magnetic parameter hysteresis curve |
