Abstract: PURPOSE: A track seek servo control method and a device of a disk drive, considering an acceleration change are provided to move a transducer to a target track by using an acceleration locus of a function where an acceleration change becomes 0 in track seek start and end parts during a track seek control, thereby shortening a track seek time while reducing mechanical vibration and noise. CONSTITUTION: A seek locus generator(60) operates a design position value, a design speed value, and a design acceleration value. A state estimator(62) determines a substantial position value, a substantial speed value, and an acceleration value. The first adder(64) subtracts the substantial position value from the design position value, and outputs the subtracted result. A position control gain compensator(66) multiplies the outputted result by a position gain, and generates a position compensation value. The second adder(68) subtracts the substantial speed value from the design speed value to output the subtracted result. A speed control gain compensator(70) generates a speed compensation value. The third adder(72) subtracts the substantial acceleration value from an added value of the speed compensation value and the design acceleration value, and generates an acceleration compensation value. An actuator(76) varies a current supplied to a voice coil.
