    摘要: A disk surface has a keep-out region and a certified region. A transducer associated with the disk surface writes servo information in the keep-out region under control of a servo track writer. The transducer then writes data in a temporary utility zone in the keep-out region. Next, a self-servo write operation uses data in the temporary utility zone to write servo information in the certified region. Thereafter, data is transferred from the temporary utility zone to a final utility zone in the certified region.
