Optically assisted magnetic recording and surface potentials were studied.1)Test spindle system for the optically assisted magnetic recording was designed and built. Adjust method for magnetic heads with optical spots were proposed and tested with disks which were coated with lubricants.2)Recording media for the optically assisted magnetic recording were investigated. A TbFeCo film stacked on FePt particls was proposed as the optically assisted magnetic recording.3)Surface potential measurement system was designed and built. The fundamental characteristics of the designed system was investigated.

对光辅助磁记录和表面电位进行了研究。1)设计并搭建了光辅助磁记录测试主轴系统。提出了光斑磁头的调整方法，并在涂有润滑剂的磁盘上进行了试验。2)研究了用于光辅助磁记录的记录介质。提出了将TbFeCo薄膜堆积在FePt颗粒上作为光辅助磁记录的方案。3)设计并搭建了表面电势测量系统。研究了所设计系统的基本特性。
