Abstract
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.
