本文论述了提高磁盘驱动器容量的方法以及当前各种磁记录介质,特别是金属薄膜介质,在高密度化磁记录技术中的状况;提出了垂直记录方式用于硬盘的关键在于开发适于垂直记录的环形磁头。着重推荐了化学镀制造金属薄膜介质的工艺要点,并指出国内近期开发金属薄膜介质的化学镀工艺是适宜的。 This article discusses ways to improve the capacity of disk drives and the current status of various magnetic recording media, especially metal thin film media, in high-density magnetic recording technology. The key to using vertical recording for hard disks lies in developing a system suitable for vertical recording Ring head. The paper mainly points out the key points of electroless plating for manufacturing metal thin film media and points out that it is appropriate to develop the electroless plating technology of metal thin film in China recently.
