Abstract: PROBLEM TO BE SOLVED: To realize stable driving control of an objective lens driver which constitutes an optical head device and has a driving mechanism with three shafts or more including the driving shafts in the focusing direction and the tracking direction. SOLUTION: The objective lens driver 6 is provided with a movable part 7 which holds the objective lens 5 and is position-controlled in the focusing direction and the tracking direction with respect to a disk 2 is provided with a driving mechanism 9 for rotating the movable part 7 around the shaft with respect to a plane almost parallel with the disk 2, including the direction along a disk radial direction. By supplying a driving signal with a waveform obtained by combining a direct current voltage component or a low frequency alternating current component and high frequency alternating current voltage component to a driving coil constituting the driving mechanism 9, the influence of static friction in the driving mechanism 9 is relieved and an influence resulting from having a hysteresis characteristic in relation to a position and an angle corresponding to a driving voltage value is reduced.

Abstract: PROBLEM TO BE SOLVED: To simplify the shape of a position regulating ramp which guides the read-write head in a hard disk drive of a dynamic loading/unloading system.
SOLUTION: The head actuator 6 is formed in a shape that its suspension 4 is articulated with the arm body 5 in the direction approaching the disk 2. The suspension 4 has a read-write head 3 at its end and a lift tab 12 disposed closer to its root than the the head 3. The position regulating ramp 7 has a slope 7a extending along the trajectory of the lift tab 12 which moves as the head actuator 6 turns. By inflecting the head actuators 6, the slope 7a for a surface of the disk 2 and the slope 7a for the other surface of the disk 2 can be formed in one body and disposed outside the disk 2.
