In a magnetic head transferring device of a hard disk drive, a rotor (300) is rotatably installed on a base (10) and has a magnetic head (500) for recording/reproducing information on/from the disk (200) mounted at one end thereof. A stator (400) is installed on the base (10) for actuating the rotor (300) to move across a parking area (210) and a recording area (220) formed on the hard disk (200). First and second magnetic members (610, 430) are respectively installed at one side of the rotor (300) and the stator (400) and are magnetically coupled to one another when the magnetic head (500) is positioned in the parking area (210) of the hard disk (200) so that the rotor (300) is locked to not move. Also, a pushing unit (210) for gradually pushing the rotor (300) by pressing the same in a direction such that the first and second magnetic members (610, 430) are separated during unlocking thereof is provided. Thus, since the unlocking mechanism of the rotor (300) is made slowly and smoothly by using a bimetal member (720), the impact and excessive rotation of the rotor (300) during unlocking thereof can be prevented. <IMAGE> |
