ABSTRACT:
The operation of the changing mechanism is set to enhance the intensity of the urging force if the acceleration sensor detects an impact. The head slider is urged against the surface of the recording medium with the urging force of a larger intensity. Accordingly, the head slider is allowed to keep contacting the recording medium irrespective of the impact. The head slider is thus prevented from jumping up from the surface of the recording medium. A collision is surely avoided between the head slider and the recording medium. In addition, the head slider is urged against the surface of the recording medium when the recording medium stands still. The head slider is completely prevented from dropping onto the recording medium.
