1.浮动磁头的动作原理磁盘存储器用的浮动磁头安装在浮动块上,靠旋转的磁盘和空气的粘滞力压缩浮动块-磁盘间隙中的空气,从而产生压力使浮动块浮动。大多数高密度的磁盘装置要求浮动块和磁盘之间稳定地形成1μ左右的间隙。从磁记录、读出原理上来看,这个浮动间隙会引起间隙损失,特别是记录介质上的波长变短时,损失更为严重,这是进行高密度记录的一个障碍。因此,希望浮动间隙尽可能地小,但实际上由于磁盘表面和浮动块表面的平面度、空气中的灰
1. Floating magnetic head principle of operation Disk storage floating head mounted on the slider, by rotating the disk and the viscous force of the air compression slider - disk gap in the air, resulting in pressure to make the slider floating. Most high-density disk devices require stable formation of a gap of about 1 μ between the slider and the disk. From the perspective of magnetic recording and readout, this floating gap can cause a gap loss. Especially when the wavelength on a recording medium is shortened, the loss is more serious, which is an obstacle to high-density recording. Therefore, it is desirable for the floating gap to be as small as possible, but in practice due to the flatness of the surface of the magnetic disk and the surface of the slider,
