    摘要: A rotary information recording/reproducing apparatus has a carriage rotatable by the first and second driving coils about an axis that moves an information recording/reproducing head radially to an associated recording disk for head positioning relative to the disk. The angle between a line connecting the center of the first driving coil and the center of the carriage pivot shaft and a line connecting the head and the center of the carriage pivot shaft is set to be not greater than 90 degrees while the angle formed between the first and second driving coils about the center of the carriage pivot shaft is within the range of from 100 degrees to 150 degrees, whereby reduction in the size and thickness of the apparatus can be achieved. A magnet-yoke assembly, which is subject to a reaction force, is mounted to a base by sheet springs and reaction-force damping members interposed therebetween so that the magnet-yoke assembly is independent from and infinitesimally rotatable relative to the base. The provision of the two driving coils and the reaction-force damping members effectively prevents the carriage pivot system and the disk spindle from being excited by the reaction force to thereby assure a high-speed and highly-accurate head positioning.

    摘要: A motor control apparatus that drive-controls a motor by an inverter based on each-phase duty command values of PWM and detects each-phase motor currents of the motor by a one-shunt type current detector. The apparatus includes a current detection correcting section that calculates a current detection correction value based on a power-supply voltage of the motor, each-phase duty command values, a back-EMF information of the motor, each-phase motor currents detected by the current detector, arrangement information of the PWM, and electric characteristic formula of the motor, thereby to correct the each-phase motor currents detected by the current detector to a motor average current by the current detection correction value and drive-controls the motor.

    摘要: An image display control device calculates a lighting luminance after reduction in luminance and an image correction coefficient by real-time calculations of a common calculator. The common calculator is controlled by microcodes stored in a code table. When correcting an image, chroma correction is enhanced to suppress a decrease in chroma due reduction in luminance, and a flicker is prevented by series infinite impulse response (IIR) filtering processes. When the image has a low average luminance but has a high chroma, a decrease in chroma is suppressed by limiting a reduction in lighting luminance.
