| 20100265613 | SERVO 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 |
| 20100315910 | ENCODER CAPABLE OF COMPENSATING FOR TILT, HARD DISK DRIVE USING THE SAME, AND SERVO TRACK WRITING SYSTEM FOR THE HARD DISK DRIVE - An encoder is capable of being used to compensate for the tilting of a movable object in an apparatus. The encoder includes a fixed scale, and a movable scale integrated with an object that moves during an operation of the apparatus and having a plurality of patterns that are out of phase from each other with respect to the direction of movement of the object. The encoder may be employed by a hard disk drive (HDD) and a servo track recording apparatus. The movable scale is integrated with an actuator arm of the HDD for positioning a read/write head of the HDD, and the fixed scale is fixed to the housing of the HDD.
