Provided is a self servo writing method of writing a final servo signal based on a reference servo signal in a hard disk drive, and more particularly, a method of writing a uniform final self servo signal by compensating for a non-uniform width of tracks where a reference servo signal is written, a hard disk drive using the method, and recording medium storing the method. The self servo writing method includes measuring the width of a target track based on the reference servo information, calculating the deviation between the measured width and a target width, and writing the final servo information while following the target track based on the center position of the target track calculated using the reference servo information and the calculated deviation of track width. According to the self servo writing method, the final servo information is written on tracks having a uniform width, even if the reference servo information is written on tracks having a non-uniform width.
