A head crash happens when the surface of the read-write head or particles on its surface contact the magnetic disk surface.
当读写头的表面或表面上的微粒与磁盘表面接触时会发生磁头划伤。
Now, if the current is sent one way through the read/write head the area is polarized in one direction.
如果当前通过读写头来发送指向一个方向的信息,这个区域的磁极指向某个方向。
So as the particles on the disk that get the current in the read/write head moving put together millions of these magnetized segments and you've got a file.
通过读写头你就可以得到每个粒子的极性,如果把这些上百万粒子的信息,汇聚要一起就够成了一个文件。
Let's try to do part of it in the head, so I can just write down the answer.
让我们先试试前面的一部分,我就直接写答案了
