摘要： A hard disk drive has a disk, a spindle motor for rotating the disk, a head stack assembly including a swing arm and a head slider disposed at a leading end of the swing arm, and a controller operatively connected to the head slider. The head slider is positioned by the swing arm over the disk and floats in such position during a read/write operation in which data is being read from or written onto the disk. The head slider has a head slider body, a magnetic head embedded in the body, and at least one resistive heating element that generates heat when current is supplied thereto. The heat causes the body of the head slider to thermally expand in such a way that the profile of the disk-facing side of the body of the head slider changes. The controller controls the height of the head slider relative to the disk by controlling the supplying of current to the resistive heating element(s). First, the controller measures the distance between the head slider and the disk during a read/write operation, and compares the measured distance with a predetermined optimum distance or allowable range of distances. Current is supplied and/or cut off from the resistive heating element(s) when the measured distance is different from the predetermined optimum distance or is outside the predetermined range of distances.
摘要翻译：硬盘驱动器具有盘，用于旋转盘的主轴电机，包括摆臂的头部堆叠组件和设置在摆臂的前端的头部滑块，以及可操作地连接到磁头滑块的控制器。磁头滑动器通过摆臂定位在磁盘上并且在读/写操作期间在读/写操作期间浮动在该位置，在该操作中数据被从磁盘读取或写入磁盘。磁头滑动器具有磁头滑块体，嵌入在主体中的磁头，以及至少一个在向其提供电流时产生热的电阻加热元件。热量导致磁头滑块的主体以这样的方式热膨胀，使得磁头滑块的主体的面向盘的侧面的轮廓改变。控制器通过控制向电阻加热元件供应电流来控制磁头滑块相对于磁盘的高度。首先，控制器在读/写操作期间测量磁头滑块和磁盘之间的距离，并将测量距离与预定的最佳距离或允许的距离范围进行比较。当测量的距离与预定的最佳距离不同或者处于预定的距离范围之外时，电流被提供和/或从电阻加热元件切断。
