In the production process of hard disk drive (HDD), there is a process of writing servo signals on magnetic disks to move the head to target address. However, conventional servo track writer takes longer time to draw servo signals because of recent increase of the capacity of HDD. Therefore, they desire a low-cost method to draw servo signals. In order to resolve the problems, self servo track writing...
