Abstract: 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.

A voice coil motor of a hard disc drive comprises a voice coil(121), a first magnet(123A), and a second magnet. The voice coil is positioned at the rear end portion of an HSA. The first magnet is positioned on or under the voice coil to create a magnetic field around the voice coil. The second magnet guides the magnetic force line of the magnetic field created around the voice coil into a vertical line. The second magnet is positioned at the opposite side of the first magnet and the thickness thereof ranges from 0.1 to 1 millimeter. The intensity of magnetic force for the first magnet is stronger than that of the second magnet. The second magnet is attached to the inner surface of a cover member(103) for the hard disc drive and a base member(101).

Abstract: An HDD(Hard Disc Drive) and a manufacturing method thereof are provided to fix a position of an upper VCM(Voice Coil Motor) block of a VCM by using a crash stopper for limiting a pivot range of an actuator. Outer circumference parts of a base member(101) and a cover member are mutually combined to form an internal space. An actuator is installed on the base member(101) to be capable of being pivoted. A VCM(140) has a lower VCM block(141) and an upper VCM block(150). The lower VCM block(141) and the upper VCM block(150) are mutually separated so that a rear end part of the actuator is inserted between the lower VCM block(141) and the upper VCM block(150). A crash stopper(160) impacts against the rear end part of the actuator, and limits a pivot range of the actuator. An upper end part of the crash stopper(160) is contained in the upper VCM block(150) to prevent the position change of the upper VCM block(150) by disturbance.
