防止头盘撞击是磁盘存储器正常使用的前提。改善盘面的加工和涂布,加强空气过滤以及提高磁头和磁层的耐磨性能当然是防止头盘撞击的基本手段,但是这些手段受到客观条件的限制。几微米的浮动间隙中积有灰尘、盘面加工不良、磁头浮动状态异常等都可能引起头 To prevent the first disk crash is the normal use of disk memory. Of course, improving the processing and coating of the disk surface, enhancing the air filtration and improving the wear resistance of the magnetic head and the magnetic layer are, of course, the basic means of preventing head disk impact, but these methods are subject to objective conditions. A few microns of floating gap in the accumulation of dust, disk processing poor, abnormal floating head conditions may lead to head
