The formation and evaluation on highly functional thin films by various methods such as sputtering, evaporating and plating were studied on the basis of the application of them to ultrahigh density magnetic recording media and heads for perpendicular magnetic recording system. The microstructure of thin films for the media and head has to be controlled with crystal and also atomic structure level, and also the design considering the read/write systems should be paid to the structure control. On the basis of such idea, the research group discussed the media consisted of different methods such as Co ferrite, Ba ferrite, electroless Co alloys, and also the combination of some heads.In those systems, one of the optimum systems, double layered media with very thin quasi-soft underlayer with a combination of ring type head is proposed. The microstrucure of media is also analyzed to be composed of Co base magnetic particles dispersed in the non-magnetic components. Such results were discussed at our several meetings.

在超高密度磁记录介质和垂直磁记录系统磁头应用的基础上，研究了溅射、蒸发、镀膜等方法制备高性能薄膜的方法及其评价。介质和磁头用薄膜的微观结构既要从晶体结构水平控制，也要从原子结构水平控制，同时考虑读写系统的设计也要注意结构控制。基于这种思想，课题组讨论了Co铁氧体、Ba铁氧体、化学钴合金等不同方法组成的介质以及几种磁头的组合，在这些系统中，提出了一种最优的系统，即具有超薄的准软底层的双层介质和环形磁头的组合。分析了介质的微观结构，认为介质是由分散在非磁性成分中的钴基磁性颗粒组成。这样的结果在我们的几次会议上都讨论过。
