Patent number: 8395856Abstract: 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.Type: GrantFiled: April 14, 2010Date of Patent: March 12, 2013Assignee: Seagate Technology InternationalInventors: Ha Yong Kim, Dong Ho Oh, Chul Woo Lee

Publication number: 20100297364Abstract: 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.Type: ApplicationFiled: May 20, 2010Publication date: November 25, 2010Applicant: Samsung Electronics Co., Ltd.Inventors: Yoon Chul CHO, Cheol-Soon Kim, Ha Yong Kim
