Abstract
A method and apparatus for writing a servo signal for controlling the position of a head on a disk during the manufacture of a hard disk drive. The present invention provides a method and apparatus for writing servo information on a magnetic disk through a magnetic head by driving an actuator of a hard disk drive (HDD) directly without employing a servo writer using control of a laser. Furthermore, when there is need for increasing the density in tracks per inch (TPI) to obtain a high capacity HDD, HDD manufacturers do not have to produce a new servo writer, thereby reducing production cost.
