Abstract
In a disk drive that includes a magnetic head and a flexible printed circuit board (FPCB) coupled to an actuator for the magnetic head, a method of writing servo information includes: receiving a signal based on an electrical property of a material included in the FPCB, wherein the electrical property of the material changes as the actuator moves; determining a radial position of the magnetic head relative to a disk of the disk drive based on the signal; and controlling a radial velocity of the magnetic head relative to the disk of the disk drive based on the radial position.
