为了提高硬盘介质的可靠性，特别是耐腐蚀性能，我们尝试了降低高覆盖、高润滑剂粘接比介质的表面能。在这项研究中，我们对一种介质的紫外线处理进行了研究，波长为172纳米，比通常使用的低压汞灯的波长短，后者的辐射波长为185纳米和254纳米。我们发现，在172纳米辐照的情况下，耐腐蚀性能得到了显著改善。本文讨论了改进的耐蚀性能及其机理。
In order to increase the reliability of hard disk media especially for corrosion-resistant property, we have tried lowering the surface energy of a media with high coverage and high bonded ratio of lubricant. In this study for the UV treatment of a media we examined the wavelength of 172 nm that is shorter than that of the low-pressure mercury lamp normally used, which irradiates at wavelengths of 185 nm and 254 nm. We found a drastic improvement in corrosion-resistant property in the case of 172-nm irradiation. In this paper improved corrosion-resistant property and its mechanisms are discussed.
