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 using a servo track writer. The read head reads the spiral servo
information and is used to position the write head, which writes a small
band of final servo information onto the disk surface. The small band of
final servo information may be embedded servo information. Importantly,
the small band of final servo information is not written using the servo
track writer. The write head is also used to write self-servo write
instructions into the small band of final servo information.
Subsequently, the self-servo write instructions are read and a self-servo
write operation is performed using the spiral servo information.
