Title: Method of controlling flying of magnetic head and device therefor in hard disk drive

Abstract: A magnetic head flying controlling device in a hard disk drive including a swing arm which is pivoted by a voice coil motor, a suspension combined with the swing arm for supporting a magnetic head, a first sensor installed on the body of the suspension, for detecting a vertical displacement of the suspension as a signal, a second sensor installed on the body of the suspension, for detecting a horizontal displacement of the suspension as a signal, a control circuit portion for halting the recording or reproduction of the magnetic head based on signals output from the first and second sensors while at the same time storing the halted position of the magnetic head, and generating a control signal for controlling the operation of the magnetic head, and a magnetic head flying actuator for controlling the driving of the magnetic head based on the control signal.
