摘要： 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.

摘要： A self-servo reference signal including a timing pattern and an oblique phase pattern is transferred in advance on a magnetic disk 1 by magnetic printing. A phase difference detection section 13 detects a phase difference between the two patterns to detect the position of a magnetic head 2.

摘要： The information recording and reproducing apparatus includes: a recording medium including a plurality of concavo-convex pits; a light source for emitting laser light; a section for changing an optical characteristic value of the laser light, using interaction between the laser light and the recording medium; and a light detector for detecting the optical characteristic value of the laser light after the interaction occurs, and then outputting a signal in response to the detected optical characteristic value. The section for changing the optical characteristic value includes an evanescent wave generating section for generating an evanescent wave from the laser light. The evanescent wave generating section changes the optical characteristic value in accordance with how much the concavo-convex pits of the recording medium influences the evanescent wave. Multivalued data is reproduced on the basis of the signal from the light detector. The multivalued data corresponds to the dimension of the concavo-convex pits measured along the direction normal to the recording medium.
