PURPOSE: A method for writing an embedded servo of an HDD(Hard Disk Drive) is provided not to use a servo writer using a laser controlling to directly drive an actuator and to record servo information on a magnetic disk, so as to reduce the production cost when the HDD enhances a TPI(Track Per Inch) for a high capacity. CONSTITUTION: An HDD(Hard Disk Drive) moves an actuator attaching magnetic heads, to be contacted with an external stopper, and locates the magnetic heads in an utmost outer track on corresponding disk surfaces, by a servo information recording control command. The HDD records corresponding location identification information in an area as much as a half of the utmost outer track, by the servo information recording control command. The HDD moves the heads to be located in an area as much as a remaining half of the utmost outer track, to an inner direction, by using the recorded location identification information as a location controlling value. The HDD records the location identification information in a location moved as much as the remaining half of the utmost outer track, by using the heads. The HDD sequentially moves the heads to the next inner track and records the location identification information, and servo-writes the entire track.
