20090268331HARD DISK DRIVE AND SERVO TRACK WRITING SYSTEM FOR THE SAME - A hard disk drive includes a housing including a base member and a cover member, a spindle motor disposed in the housing, a data storage disk disposed on the spindle motor, an actuator disposed in the housing to move a read/write head to a position on the data storage disk, a clock signal providing unit disposed on the data storage disk to provide a clock signal of the data storage disk, a position signal providing unit disposed on the actuator to provide a position signal of the actuator, and first and second windows disposed in the housing to correspond to the clock signal providing unit and the position signal providing unit.10-29-2009
20100053805HARD DISK DRIVE AND METHOD OF MANUFACTURE - A method of manufacturing a hard disk drive includes measuring an imbalance value including an imbalance position with respect to a rotation center of a rotation shaft of the hub, with respect to each of a plurality of disks installed on a hub of a spindle motor to rotate the disks, allowing different imbalance positions of the disks to approach each other in a circumferential direction by applying an impact to the hard disk drive, and correcting the imbalance value by applying an impact to the hard disk drive in a direction opposite to the imbalance positions of the disks approaching each other with respect to the rotation shaft of the hub, to move the imbalance positions of the disks approaching each other in a radial direction of the disks with respect to the rotation center of the rotation shaft of the hub.03-04-2010
20100265613SERVO PATTERN ERASING METHOD AND APPARATUS OF HARD DISK DRIVE - A method of erasing a servo pattern of a hard disk drive includes reading a servo pattern recorded on a disk, generating an erase pattern to erase the servo pattern based on the servo pattern obtained in the reading of the servo pattern, and erasing the servo pattern by using the erase pattern while the disk is rotated. The servo pattern recorded on the hard disk drive may be uniformly erased. Also, a stabilization time to stabilize a read/write head after the position control of the read/write head that is needed when a servo writer is used may be avoided so that a time to erase a servo pattern may be reduced.10-21-2010
20100265614SERVO PATTERN WRITING METHOD OF HARD DISK DRIVE - A method of writing a servo pattern in a hard disk drive includes manufacturing a master pattern, and writing the reference servo pattern to the disk by using the master pattern and a magnet for magnetizing the disk. The master pattern includes a plurality of ammonite cycles that have substantially the same pattern as the reference servo pattern and are radially formed from the outside toward the inside of the disk. A final servo pattern may be written using the reference servo pattern.10-21-2010
20100297364SERVO PATTERN FORMING METHOD OF HARD DISK DRIVE - A servo pattern forming method of a hard disk drive includes magnetically printing a reference servo pattern, which has different features according to zones divided along a radial direction of a disk, on the disk, and recording a final servo pattern in the disk on the basis of the reference servo pattern. As a result, the quality of a final servo pattern can be enhanced by preventing an amplitude drop that arises in an ID zone of the disk when a reference servo pattern is recorded using a conventional servo track writer.11-25-2010
