Abstract: A method for servowriting a magnetic hard disk drive includes servowriting a first servo burst pattern by using a servowriter coupled to a head-disk assembly within a clean room environment, self-writing at least a second servo burst pattern radially offset relative to the first burst pattern by reading the first burst pattern without using the servowriter, and self-writing a final burst pattern by using the first burst pattern and the second burst pattern without using the servowriter. One or more intermediate burst patterns may be provided to accommodate writer/reader offset of dual element read heads in order to produce final product servo burst patterns. A disk drive having embedded servo sectors each including an untrimmed six-burst final servo pattern is also disclosed. The disk drive self-writes at least some of the final servo pattern.

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.
