A method is provided for adjusting a track-seeking compensation coefficient during movement of an optical pick-up unit to a target track position on an optical disk. According to the compensation coefficient to calculate a first number of tracks (T 1 ) to move the pick-up unit in a first orientation. Then, calculate a second number of tracks (T 2 ) for moving the pick-up unit to the target track position in a second orientation. When T 2 is larger than a first tolerance, according to the judgment of whether the two orientations are the same, selectively use an upper and lower bounds to adjust the compensation coefficient for next seeking operation. Calculate a third number of tracks (T 3 ) with T 1 and T 2 , and calculate a fourth number of tracks (T 4 ) with the adjusted compensation coefficient. The compensation coefficient may be further adjusted repeatedly until the difference of T 3 and T 4 is less than a second tolerance.
