ABSTRACT:
The present invention is directed to a method and apparatus for performing a self-servo write operation in a disk drive. In one embodiment, the disk drive includes a disk surface having a read head and a write head associated therewith. Spiral servo information is written onto the disk surface in a closed-loop fashion through use of a servo track writer. The read head reads the spiral servo information and is used to position the write head, which writes final servo information onto the disk surface. The final servo information may be embedded servo information. The final servo information that has been written onto the disk surface looks substantially identical to a disk surface that has had its final servo patterns written using a servo track writer.
