摘　　要：本文分析了硬磁盘以及近场记录光盘记录密度与浮动间距之间的关系 ,在分析对比的基础上 ,得出了在同等浮动间距的情况下 ,近场记录光盘面记录密度比硬磁盘高大约 2 8倍 ;在同等面记录密度的情况下 ,对硬磁盘浮动性能的要求比近场记录光盘高近 10倍的结论 .This paper analyses the relationship between the recording areal density and the floatingspace for hard disk and near-field recording disk respectively. Based on the comparisons, we draw a conclusion that the recording areal density for near-field recording disk is more than 28 times of that of hard disk with the same floating space, and with the same areal density the requirement for the floating space of hard disk is 10 times more serious than that of near-field recording disk.
