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： A hard disk drive includes a magnetic head to write data to a disk by magnetizing the disk using a leakage magnetic flux that leaks in a disk direction through a write gap provided between a write pole to apply a magnetic field to the disk and a shield provided separately from the write pole, and an actuator arm allowing the magnetic head to pivot over the disk. In the hard disk drive, the write gap is asymmetrically formed to a left and a right with respect to a center axis line of the write pole according to a movement direction of the magnetic head when the magnetic head pivots over the disk.
