method for controlling the flight of a magnetkopfes and related device in a hard disk drive

摘要

A magnetic head flying controlling device for use in a hard disk drive, comprising a first sensor (250) for detecting a vertical displacement of a suspension (240), and a second sensor (260) for detecting a horizontal displacement of the suspension; and a control circuit (30) for halting the recording or reproduction of the magnetic head based on signals output from the first and second sensors, i.e. when an impact or vibration is detected, and stores the halted position of the magnetic head.
