摘要： A magnetic disk apparatus includes: a driving unit; and control part configured to control the driving unit. The control part includes: a position error feedback control system and a two-degree-of-freedom control system. The position error feedback control system has an integrator and a phase-lead compensator and is operative to determine a position command based on a target position and a sensed position of the magnetic head, thereby performs feedback control on the driving unit. The two-degree-of-freedom control system receives as input a target moving distance of the magnetic head and outputs a current command to the driving unit by using a mathematical model of the driving unit. The control part updates the mathematical model, and has a first update mode in which the mathematical model is updated using the output of the phase-lead compensator while the output of the integrator is provided to the driving unit.

摘要： A magnetic recording apparatus includes a composite magnetic head which includes a recording head and a reproducing head; a magnetic storage medium; a discrete area; and a correction information recording area. Positioning correction information is able to be written in the correction information recording area at each track center. The apparatus also includes a center shift amount detection area. Center shift amount detection information is previously recorded in the center shift amount detection area. The center shift amount detection information is for measuring a center shift amount which indicates a relative distance between a tracking center and an actual track center of the discrete area when either the recording head or the reproducing head is positioned at a track center.

摘要： A ramp-unloading seek control device includes a voice coil motor, a detector, an instruction-current detector, a head-speed computing unit, and an identification structure. The identification structure estimates an error between a true resistance value and an estimated resistance value of the voice coil motor. The identification structure can minimize an estimated error defined as a difference between an estimated value ŷ(k) of the head speed and the head speed y(k), and employs {circumflex over (b)}1 to calibrate the estimated error. {circumflex over (b)}1 is determined by minimizing the estimated error. ŷ(k) and y(k) are defined by the equation (A): ŷ(k)=−â1y(k−1)+{circumflex over (b)}0u(k−1)+{circumflex over (b)}1u(k−2) (A). y(k−1) denotes a head speed computed by the head-speed computing unit at the last sampling time. k denotes the present sampling time. u(k−1) and u(k−2) denote instruction currents at the last sampling time and the last but one sampling time, respectively. Unknown variables â1, {circumflex over (b)}0 are determined by minimizing the estimated error.
