    • A disturbance compensation signal is produced by estimating the magnitude of disturbance acting upon an actuator based on a driving signal and a voltage signal generated when driving the actuator. A control signal is produced by multiplying the disturbance compensation signal by a gain adjustment coefficient. A head position error signal is produced based on the target position of a magnetic head and the current position of the magnetic head that is detected based on servo information recorded in advance on a magnetic disk. A gain adjuster obtains the driving signal by adding together the control signal and a position control signal. The actuator is driven with the driving signal output from the gain adjuster.

    • A diaphragm structure includes a ceramic substrate having at least one window portion and a thin diaphragm laminated onto the ceramic substrate so as to cover the window portion, wherein only a part of an interface between the ceramic substrate and the thin diaphragm is joined to form a joint of the diaphragm. A diaphragm structure is free from instability caused by a breakage or deformation of a partition wall between window portions upon punching or laminating even if a diaphragm structure employs a design in which dimensions of a diaphragm portion is maintained and simultaneously a distance between diaphragm portions is made narrow to restrain a surface area excluding a diaphragm portion of a diaphragm structure or a design in which a plurality of diaphragm portion having various configurations and dimensions are disposed.

    • A position detector generates a position error signal corresponding to a current position of a head, a position controller generates a position control signal from the position error signal, a voltage detector detects a voltage signal generated when driving an actuator by a driver, a disturbance estimator generates a disturbance estimation signal from a driving signal and the voltage signal, and a corrector outputs the driving signal from the disturbance estimation signal and the position control signal. The disturbance estimator includes a comparator which compares the disturbance estimation signal with a voltage signal and which outputs a deviation signal, and an adder which adds a signal obtained by multiplying an integral signal, which is obtained by integrating the deviation signal, by a first coefficient and a signal obtained by multiplying a proportional signal proportional to the deviation signal by a second coefficient, and which generates the disturbance estimation signal. The disturbance estimation signal suppresses a tracking deviation of the head due to a disturbance such as an inertial force applied to the head actuator and stabilizes head positioning control.
