  • Self-writing of servo patterns based on printed reference pattern in rotating disk drive
    Patent number: 6304407
    Abstract: A coarse magnetic template pattern is transferred to a data storage surface of a disk by magnetic printing techniques. As printed, the template pattern essentially provides clocking and may provide radial position information. The disk is then assembled into a completed and enclosed disk drive. The template pattern is then used by the disk drive to self-write highly resolved product embedded servo patterns onto storage surfaces of each data disk including the surface having the printed template pattern.
