Method and apparatus for compensating torque variation according to temperature in seek servo

The present invention relates to a disk drive controlling method and apparatus, in particular, compensation torque change process according to the temperature in the seek servo to compensate for the difference between the modeled torque constant and the actual torque constant used for the servo design according to the temperature changes in the disk drive, and to a device. Seek servo temperature torque compensation method according to in accordance with the present invention, torque in the disk drive control method, corresponding to the detected gain of the seek control loop for generating a seek drive current applied to the voice coil in the seek mode, the temperature It characterized in that the control to vary in accordance with the constant temperature correction value.
