ABSTRACT:
A disk storage device comprises a microcomputer for estimating an external disturbance compensation signal and storing it and a first adder for adding the external disturbance compensation signal as a feedforward signal to a positioning compensation signal to a drive circuit. Where a positioning compensator for estimating a velocity signal based on a drive signal is provided, a difference signal between the drive signal and a signal proportional to the external disturbance compensation signal, instead of the drive signal, is applied to velocity estimation unit for correction.
