A method of positioning a magnetic head on a target cylinder of a magnetic disk uses a position signal derived from a servo signal which is read from a magnetic disk using a magnetic head. The servo signal includes at least first and second servo signal components on even cylinders of the magnetic disk and includes at least third and fourth servo signal components on odd cylinders of the magnetic disk. The position signal is used for moving the magnetic head to a desired cylinder. The method comprises the steps of obtaining a first position signal for positioning the magnetic head to an odd cylinder on the magnetic disk based on a difference between peak values of the first and second servo signal components, obtaining a second position signal for positioning the magnetic head to an even cylinder on the magnetic disk based on a difference between peak values of the third and fourth servo signal components, and using only one of the first and second position signals to position the magnetic head to the target cylinder depending on a cylinder address of the target cylinder.
