Abstract
An offline self servo writing method capable of improving servo writing accuracy and reducing copying time by designing a servo pattern of a reference disk to have the same resolution as a final servo pattern, and a disk drive using the method. The offline self servo writing method includes a servo information writing process performed after a reference disk, where a reference servo pattern having the same resolution as a final servo pattern, is written and one or more blank disks are assembled in the disk drive, wherein the servo information writing process is performed by simultaneously writing identical final servo information on all disks including the reference disk by using the reference servo pattern while following tracks of the reference disk.
